TECHNICAL FEATURE New Procedures to Structural Realignment: ©iStockphoto.com/sumbul The Lack of Basic Anchoring Procedures Can Kill Your Productivity By Larry Montanez III, with Peter Pratti Jr.* Part One At almost any gathering where someone mentions a car accident, I hear him or her say, “They don’t make them like they used to.” My response is always the same: “Thank God for that!” The complexity of today’s vehicles has made them not only safer, but also smarter. Most late-model vehicles are built with sensors and computers that can determine if an accident is about to happen. Those same computers will put the vehicle into a pre-safe mode that will brace the vehicle for the collision, to protect you just in case that accident happens. If such an incident occurs, the vehicle’s Supplement Restraint System will tighten seatbelts to remove slack, deploy airbags and cushion the blow to the occupants. All this happens by sensors sending information to the multiple computer control modules in thousandths of a second. What’s most important – and yet, somehow overlooked — are the structural changes in the late-model vehicles that assist these sensors and computers in providing safety in the vehicle. I would like to take a moment to go over the history of the automobile, and how far we have advanced. Back in 1885, Karl Benz built the first practical automobile powered by an internal-combustion engine. This became the design used to build a gas-fueled car, which was a three-wheeler (1886). This three-wheeled car later became the design for the first fourwheeled car in 1891. Karl Benz’s design led to the first massproduced vehicle in the United States, designed by Ransome Eli Olds (Oldsmobile) in 1901. In 1946, an inventor, entrepreneur and design engineer by the name of Preston Thomas Tucker attempted to produce a vehicle that was the first to be designed with a rear engine, pop-out windows, seat belts, a soft padded dashboard, Magnesium wheels, 4-wheel disc brakes, fuel injection and a directional third headlight – dubbed the “Cyclops Eye” – that would turn as you steered around corners. This all-new “Safety Designed Vehicle” was named the 1948 Tucker Sedan, also known as the Tucker Torpedo. It is amazing that Tucker had many of these innovations decades before other manufacturers even thought about using them. The Tucker Torpedo’s design and features later led to the modern vehicle design and engineering we know today. Newer vehicle designs incorporate Advanced High Strength Steels (AHSS) that add rigidity to the passenger compartment while keeping the vehicle lighter. Many call this “lightweight steel,” but there is no such thing. Steel is heavier than many other materials used in vehicle construction. The steel industry needed to compete with the aluminum industry by utilizing metallurgy to design thinner (hence lighter), but stronger steel. Vehicle design engineers are required to build vehicles that are safe and fuel efficient, at the lowest possible cost. With the steady increase of AHSS usage, the collision repair industry needs to understand the built-in collision energy management and the reparability of these new steels. There have been many articles and courses on these new steels being used, so here is a little overview on the new steels you will encounter when repairing the new vehicles coming into your shop. Note: The following definitions have been paraphrased from Wikipedia at http://en.wikipedia.org. Ultra High Strength Steel (UHSS)/ Advanced High Strength Steel (AHSS) / Boron (B) (BOR) Boron steels possess a hardness equivalent to that of much higher carbon steels and of more expensive low alloy steels. Advantages of boron steels are improved cold formability, lower delivered hardness giving improved blanking tool life, improved weld ability due to low carbon equivalents, lower tempering temperatures, giving savings on energy and good case hardening response. The type of boron steel used on February 2009 29 vehicles today has extremely high strength. The boron steel used on Volvo cars has a yield point of about 1,350-1,400 MPa (196,000-203,000 psi). That’s about four times stronger than average high-strength steel. But the process used to make it that strong takes away some of the steel’s workability properties, such as being able to straighten it. Boron alloyed parts are generally replaced in their entirety. Boron is becoming more and more prevalent in vehicles for safety in the passenger compartment. Since the 2000 model year, boron was found primarily on European vehicles, such as the dash panel beam on the 2002 Porsche Cayenne SUV, the safety bar around the rear seats on the 2003 Porsche Boxster, the door guard beams on the 2003 Porsche 911 Carrera and the inner B-pillars on the 2003 Mercedes Benz E Class. Volvo probably uses boron steel the most. Boron is used on the bumper reinforcements and door guard beams. On the current Volvo models, several applications of boron steel, including the inner B-pillar reinforcements, the roof bow between the B-pillars (if there is no sunroof ), inner and outer rear body panels, the A, B, C, D-pillars and rocker panel reinforcements for most vehicles. Honda, Nissan, Toyota, Mercedes Benz, Porsche, BMW, Dodge/Chrysler and GM, among others, are incorporating their new vehicles with many center section parts made with boron steel. Repairing, sectioning, or partial replacement of this type of steel is not recommended. Ultra High Strength Steel (UHSS)/ Advanced High Strength Steel (AHSS) / Martensitic (M) (MAR) This class of steels was named after the German metallurgist Adolf Martens (1850–1914). This most commonly refers to a very hard form of steel crystalline structure, but it is also any crystal structure that is formed by displacive transformation. Martensite steel is being used by GM in the rocker panels and floor crossmembers on many of their SUV vehicles and passenger cars. Repairing, sectioning, or partial replacement of this type of steel is not recommended by the vehicle manufacturers. Look for more manufacturers to utilize this material in the next few years. Ultra High Strength Steel (UHSS)/ Advanced High Strength Steel (AHSS) / TRIP TRIP steels are one of the newest materials being developed by the steel industry. In relation to other advanced highstrength steels, TRIP steels exhibit better ductility at a given strength level. This enhanced formability comes from the transformation of retained austenite (ductile, high temperature phase of iron) to martensite (tough, non-equilibrium phase) during plastic deformation. The acronym “TRIP” stands for Transformation Induced Plasticity. Because of this increased formability, TRIP steels can be used to produce more complicated parts than other high strength steels, allowing the automotive engineer more freedom in part design to optimize weight and structural performance. This type of steel is starting to make its way into some newer vehicles due to INDUSTRY LEGEND BILLY CARR PASSES On October 14, the Virginia auto insurance and repair communities were forever changed with the passing of William L. Carr. Affectionately known as “Billy” to friends and colleagues, Carr served as the eastern region appraisal advisor for Fireman’s Fund Insurance. Since joining the company in 1985, Carr had established a reputation throughout the industry for his good-humored nature and ability to forge friendships with repairers and insurance personnel alike. “I loved having Billy walk into my shop,” says WMABA Immediate Past President Mark Boudreau. “I 30 February 2009 knew that for the next half hour to one-and-a half, I would be laughing while working.” Fireman’s Fund Appraisal Manager Bill Webb remembers Carr as a true professional willing to do whatever it took to do the job right. “Bill was one of those old-school type of guys,” he says. “He was extremely professional and got along very well with people from Florida all the way up to Maine.” Born in 1947, Carr graduated from Central Catholic in 1965 and later served a tour of duty in Vietnam. In addition to his 40-year career in the automotive industry, the formability when designing more complex parts. Repairing, sectioning or partial replacement of this type of steel is not recommended. Dual Phase/Dual Ten/DP Dual-phase steel is a high-strength steel that is heat treated to contain both a ferrite and martensite microstructure for extra strength. It is highly formable steel and has a low alloy content and high strength. The desire to produce higher strength steels with formability greater than conventional controlled rolled high strength micro alloyed steel led to the development of DPS in the 1970s. Dual-phase steel features a soft ferrite microstructure, with a matrix containing islands of martensite in the secondary phase (increasing amounts of martensite increase the tensile strength.) Dual-phase steel features a low yield ratio (i.e. yield strength to tensile strength), high tensile strength and high work hardening rate. The steel melt is produced in an oxygen top blowing process in the converter, and undergoes an alloy treatment in the secondary metallurgy phase. The product is aluminum-killed steel, with high tensile strength achieved by the composition with manganese, chromium and silicone. The martensitic phase is produced by quenching a hot cold-rolled strip before entering a zinc pot of a hot-dip galvanization unit. This has low yield strength, low yield to tensile strength ratio, high initial strain hardening rates, continuous yielding, good uniform elongation and excellent combinations of tensile strength, ductility and toughness. Dual Phase has a good capacity to absorb crash energy and an ability to resist fatigue. Chrysler, Jeep and Dodge vehicles, among others, are incorporating this type of steel into their Front Uni-Rails for added crash management. Repairing, sectioning, or partial replacement of this type of steel is recommended only at approved locations. Heat cannot be used. HSLA High strength low alloy (HSLA) steel is a type of steel alloy that provides better mechanical properties or greater resistance to corrosion than carbon steel. HSLA steels vary from other steels in that they aren’t made to meet a specific chemical composition, but rather to meet specific mechanical properties. HSLA steel is used in cars, trucks, cranes, bridges and other structures that are designed to handle large amounts of stress or need a good strength-to-weight ratio. HSLA steels are also more resistant to rust than most carbon steels, due to their lack of pearlite – the fine layers of ferrite (almost pure iron) and cementite in pearlite. Repairing, sectioning or partial replacement of this type of steel is recommended only at approved locations. Some manufacturers allow heat to be used, but this recommendation is very limited. Mild Steel (MS) Soft Steel (SS) Mild Steel, Bake Hardenable (BH) and Solid Solution Strengthened Steel (SSS) are used in very limited quantities for structural parts. These types of steel are most commonly used for closure panels such as hoods, deck lids, dash panels, The late William Carr with son Matt and grandchildren Dylan and Charli. he enjoyed spending time with his wife and two children, Jaime Leigh and William Matthew. In his time away from the field, he was known for his love of golf and billiards. He is survived by his children and two grandchildren, James Dylan and Mikhaeli Charlize. WMABA and Hammer & Dolly offer Billy’s family and friends our deepest condolences. February 2009 31 etc. These types of steels are generally the most repairable. They can usually be heated, but there are limits to the time and amount applied. Please keep in mind that if any of these steels have a “KINK,” they must be replaced. Only the steels that are repairable can be repaired if there is a “BEND.” Although one could attempt to repair a “BEND,” please keep in mind that some of the repairable types of steels might have a permanent deformation or require excessive heat to straighten, which would require replacement.

TECHNICAL FEATURE New Procedures to Structural Realignment: ©iStockphoto.com/sumbul The Lack of Basic Anchoring Procedures Can Kill Your Productivity By Larry Montanez III, with Peter Pratti Jr.* Part Two Anchoring Changes The first-known unibody/monocoque vehicle was the 1922 Lancia Lambda, which was produced until 1931. Many European vehicle manufacturers used the unibody design since the 1930s, while the American auto manufactures utilized the Body on Frame (BOF) design. Due to the lack of popularity of the European vehicle in the United States, the equipment manufacturers built BOF repair equipment. After the gas shortages of the 1970s in the U.S., GM announced their all-new “safe and fuel economical compact vehicle” for the 1981 model year named the Citation. This is when the compact unibody vehicle first started to become a mass-produced vehicle in the USA. The equipment makers of the dozer-type realignment machines for BOFs had to make changes to the current design. The dozer was a long steel beam with a spine-type tower attached to it that would pivot by pressure from a five or 10ton hydraulic ram. There were other types of realignment machines such as the vector, pot-and-pulling tower or a lip and pulling tower designs. All of these were good for that type of vehicle design at that time, but the new unibody vehicle incorporated High Strength (HSS) and High Strength Low Alloy Steel (HSLA) for the main structure of the vehicle, while the BOF utilized a different thickness of Mild Steel for strength. Since the European repair equipment manufacturers had years of experience with the unibody designed vehicles, they became more popular with the US auto collision industry. Fixture-type equipment companies such as Celette and Global Jig and universal straightening equipment companies such as Chief, CarO-Liner and Blackhawk started to sell their unibody repair equipment. Let’s look at how they anchored the unibody to their equipment. Universal Type (Car-O-Liner, Chief, Blackhawk, etc.) These repair equipment makers require the vehicle to be placed on the bench or frame rack, by driving, hoisting, or winching the vehicle onto the equipment. The vehicle utilizes the specific equipment maker’s anchoring clamps attached at the four corners of the center section of the vehicle. These anchoring clamps attach to the pinch weld or flange area of the rocker panel. In cases where there was no flange or a horizontal flange, there would be an adapter to the standard clamp or a special clamp required. Once the vehicle was secured to the equipment, the pulling towers would be moved in to position. Measurements would be compared to vehicle makers’ dimensions and structural diagnosing would begin. Fixture Bench or Dedicated Bench Type (Celette, Global Jig, Car Bench, etc.) These equipment makers require a universal clamping or dedicated fixture set. The universal type will adapt to multipletype vehicles, depending on the configuration and application. The dedicated fixtures come in a gang-type box for a specific make, model and year of vehicle. Each vehicle has directions to how to build the fixtures on the bench to create a skeletal version of the vehicle. Each fixture mounts to a specific area of the vehicle, which is also the measurement. The fixture is a specific height, and has been attached to the bench at a specific width and length; this process sets up the Datum (Height), Centerline (Width) and Zero Plane (Length). These three measurements let you know exactly how damaged the vehicle is, while also providing you with a view of where the vehicle needs to be. It is the same type of system the factory uses when building the vehicle. Structural Realignment Equipment Changes As I mentioned before, with the advent of the new ad- March 2009 31 vanced steels, repair equipment makers needed to make changes to their products. Due to the new metals, it is imperative to ensure you do not cause any collateral damage to mounting areas or the part you are pulling at the junction to adjacent parts. Due to the varying strength of the steel in the front and rear section of the vehicle, most repair equipment makers produce additional anchoring devices. Most vehicles produced today have non-repairable front sections; this includes BOFs. As you go further back on the rail, the steel gets stronger and stronger. This is accomplished by adding reinforcements inside the rail, but design engineers are also utilizing Tailor Welded Blanks more often. Tailor Welded Blanks are different thickness types of steel that are laser-welded together. Tailor Blanks allow for a transition between strengths of steel, which allows better transfer of collision energy. The only downside has been that structural realignment of these types of vehicles requires some new techniques to ensure no collateral damage. Let’s look at some of the procedures to properly structurally realign a vehicle: 1. Perform a basic structural measuring of the vehicle on a two-post lift. This can be completed quickly and before the vehicle is torn down. This provides a full picture of how damaged the vehicle is and how and where to anchor the vehicle. 2. Check with repair equipment manufacturers’ procedures for attaching and anchoring the vehicle to the bench or rack. 3. Set up your measuring system and measure the vehicle on the bench or rack machine. I know we already mentioned measuring the vehicle on a two-post lift, but your datum will change and you will need to ensure the measurements are accurate. On a dedicated or universal fixture system, this will be completed in conjunction with the anchoring. 4. Look up the repair and materials locations in Alldata or at the OEM website. Although this should have been done by the estimator, the structural repair technician will need to know what type of structural materials are utilized in each vehicle. Once the material type has been determined, the technician can now determine where they need to attach the additional clamps to anchor the vehicle. 5. After attaching the additional anchoring, you can now attach the pulling clamp to the vehicle and the pulling tower. 6. Based on the information gathered from the three-dimensional or fixture measuring, you can determine where you will need to apply pressure for pulling and additional anchoring for holding. One tip to use is to view the damage and pretend your body is the pulling tower, your hand is the clamp and your arm is the chain. Then, ask yourself the following questions: “Where would you stand to pull the vehicle?” 32 March 2009 “Where would you grab the damaged part?” “Which angle would your arm be at?” ”If you did pull the vehicle this way, what undamaged part could become damaged?” Doing this will give you a good idea if you are starting in the right place and using the correct pulling angles. As you start to apply pulling pressure, you will need to pay careful attention to the measurements, as you will need to slightly over-pull the part to prevent too much springback. The Car-O-Liner electronic measuring system has a “Bull’s-eye” view to judge over-pulling and at what angle you are pulling from. While pulling, make sure to use the hammer and wood block stress-relieving technique. A controlled amount of heat can be used if recommended by the OEM. 7. After relieving the pressure, check your measurements to see how much damage has been removed. If that pull did not remove all the damage, then you will need to make adjustments to your tower, pulling angle and clamp position. Repeat this process until the damaged part is back to OEM specifications. Providing there is no stress cracks or permanent deformations, and the OEM does not require the part to be replaced, the part is repaired. This would be true in most cases except for Boron steel, which in most cases cannot be pulled due to collateral damage. 8. After performing multiple pulls and stress-relieving techniques, you still might not achieve your desired results. This might be due to the type of steel construction such as HSS, HSLA, DP or a combination of these steels. These steels can have a tendency to “lock” the damage into that part and will not allow you to remove the damage. In this case, you might need to check all of your measurements and might have to cut the damage out and continue to pull. If all of your measurements are within OEM specifications except in the area of damage, then you should remove the damaged part and prepare for part replacement. New Part Replacement Procedures Now that the vehicle is back to OEM specifications and that damaged area is removed, you can start the part replacement process. Let’s look at some of the changes in the part replacement procedures. Some are very familiar and some are going to be new, but make the replacement process easier. 1. Doublecheck the OEM or Alldata procedure sheet. 2. Trial fit the replacement part(s) by clamping them in place and checking the measurements, welding root gap and mounting locations for bolt on parts. Now here is the NEW procedure you will most likely need to follow: a) Following the OEM and equipment makers’ instructions, install either the dedicated fixtures or universal Jigs (which may require electronic measuring to place the Jig in the correct spot) in the proper location. You will now lock those Jigs in place so that they do not move. b) Lay the replacement part on to the Jigs and attach the part to the vehicle using clamps. c) Now, you will need to check to see what attachment method is required and either make the locations for rivets, STRSW, or GMAW/MIG. d) Leave the Jigs in place, remove the part(s).

Prepare the flange area for STRSW (squeeze-type resistance spot welding), MIG/GMA, weld-bonding, adhesive bonding or any combination as per the OEM recommendations. 4. Make test welds on scrap pieces of the damaged or replacement part to ensure proper set up and weld penetration. You will also need to destructively test the welds. Make sure that you take photos of the tested welds for documentation. 5. Now, prep the flanges for adhesive bonding, seam sealer, weld through primer or epoxy primer as required by the OEM instructions. 6. Place the properly prepared part back onto the Jigs and make sure everything lines up properly. 7. Use the recommended attachment procedure.

The days of standard labor allowance for “Set Up and Measure” are over. Many of these procedures will require more time to accomplish. The amount of time required will be based on what you charge for these procedures. There will be some variables involved in your calculations, such as the Labor Rate you charge or agree to. Let’s look at an example: A 2008 Ford Explorer is going to be set up for structural realignment on a Car-o-Liner BenchRack. This vehicle has damages to the front upper body structure and the frame assembly. You will need to R&I the fuel tank, rocker mouldings and running boards and loosen the brake lines to access the anchoring areas in the center section for this equipment. Now, here are the procedures after that. (Please understand that I am going to paraphrase these procedures for space.) 1. Drive the vehicle onto the BenchRack. 2. Access the Car-o-Liner Vision X3 database for this vehicle. 3. Check the Car-o-Liner anchoring locations and the clamp configuration required. 4. Assemble the truck anchoring clamps. 5. Raise the vehicle. 6. Attach the clamps in the proper locations. 7. Attach the pull tower clamps and chains. (Remember to use the tip suggested earlier.) 8. After some preliminary pulls and measuring, access the Vision database for the EVO additional anchoring fixtures and assemble them according to the directions. 9. Attach the anchoring fixtures and continue to pull until all measurements are back to OEM specifications. 10. Remove the part and attach the proper EVO part holding fixtures. On your repair order, the procedures for the “Set Up and Measure” would be listed as separate labor procedures and not lumped into a standard amount. Using the 2008 Explorer as an example, you could itemize the structural repair as follows: * Measure for Damage Analysis/Computerized Structural Diagnosis (EME 54) * Set Up Vehicle on Realignment Apparatus * Additional Anchoring/Set Up for Upper Body/Unibody * Measure Vehicle for Repair (EME 54) * Additional Anchoring for Pulls * Fixture/Jig Set Up for Replacement of Parts Because I did not mention the type of structural damage to this vehicle, I am not going to cover pull time in detail but let’s use the following as an example: Structurally Realign Upper Body >>> Time is to realign mash, sway and sag to the Left Front Area with a Conjunctive Pull to the Right Side. Structurally Realign Frame Rails >>> Time is to realign sway and sag to the Left and Right Front Frame Rails. There are some other additional items related to this repair that will need to be listed with the structural repair such as: Remove Coatings from Rocker Panel Flange Left Remove Coatings from Rocker Panel Flange Right R&I Underbody Shield Left Side R&I Under Engine Cover R&I Exhaust/Muffler R&I Wheels for Diagnosis Repair Left Pinch Weld Flange Repair Right Pinch Weld Flange Mask Left Rocker Panel Repair Left Frame Clamp Mounting Repair Right Frame Clamp Mounting Mask Left Frame Acid Etch Primer R&I Rocker Moulding Left Side R&I Rocker Moulding Right Side R&I Underbody Shield Right Side Replace Clips Replace Hardware Exhaust R&I Wheels for Repair Refinish Left Pinch Weld Flange Refinish Right Pinch Weld Flange Mask Right Rocker Panel Refinish Left Frame Clamp Mounting Refinish Right Frame Clamp Mounting Mask Right Frame Epoxy Prime April 2009 23 O'Donnell Honda 8620 Baltimore Nat’l Pike Ellicott City, MD 21043 Parts Direct: 410-461-5972 24 Hour Fax: 410-461-9654 • • • • • Hours of Operation: M-F: 8:00am-6:00pm Sat: 8:00am-5:00pm Complete Line of Glass & Sheet Metal Your Source for OEM Honda Parts Competitive Pricing Professional Wholesale Staff Free Delivery Always Radley Chevrolet I recommend that you list each procedure and the time required to complete those procedures. This is important to ensure your calculations for structural repair are accurate and fair. All of the above procedures would be listed under “frame time” if you charge a different Labor Rate for structural repair. Now, what would you charge for these procedures and the materials required? Try it out for yourself. With the steps and procedures I’ve outlined, you will have a better understanding of the current structural materials and how it is necessary to pre-measure, anchor properly and replace parts according to the OEM recommendations for a safe and productive repair. For more information on these procedures, I would suggest you hire a consultant, attend your frame equipment makers’ classes or attend I-CAR courses such as SPS07, SPS08 and MEA01. * Additional consulting by Dave Demarest Jr 3670 Jefferson Davis Highway Fredericksburg, VA 22408 Toll Free:800-355-8202 Fax:540-891-2074 Hours of Operation: Monday -Friday: 7:30am-9:00pm Saturday: 8:00am-2:00pm 26 April 2009 Larry Montanez is a former I-CAR Instructor and is Coowner of P&L Consultants with Peter Pratti Jr. P&L conducts repair workshops on MIG & Resistance Welding, Measuring for Estimating and Advanced Estimating Skills.
