Complete Joint Penetration (CJP) – A groove weld
condition in which weld metal extends though the joint
thickness.

groove weld in which weld metal does not extend though the
joint thickness.
Concaved Root Surface – The configuration of a groove
weld exhibiting underfill at the root surface.
JLab Welder Training
22

Root Reinforcement – Weld reinforcement
opposite the side from which welding was
done.
Root Face – The portion of the groove face

23
Welding Terminology

A Closer Look @ The JLab Welding & Pressure Systems Safety Program Requirements
• Lets start by reviewing and having a brief discussion about some of
the documents (Code of Federal Regulations, Specifications, DOE
Orders, Recommended Practices, etc.) that govern and support the
requirements imposed by the DOE onto JLab as it relates to the
Quality Assurance and Quality Control processes.
• We will also review and briefly discuss several of the documents,
processes and procedures that were developed by JLab to comply
with the DOE’s requirements.

The 5 Types of Stainless Steel
Austenitic Stainless Steels. These are the most frequently used types of stainless steels. Austenitic stainless steels
tend to have a high chromium content compared to other steel alloys, giving them a higher resistance to corrosion.
Another common characteristic of austenitic stainless steel alloys is that they tend to be non-magnetic—though
they may become magnetic after cold working.

Jlab Welding Program Requirements
Going forward, welders will be required to have a copy of the Welding
Procedure Specification (WPS) that they are welding in accordance
with on-hand for review prior to starting welding operations.
JLab Welder Training
61
Jlab Welding Program Requirements
Welders will be expected to stay within the welding parameters
(amps & volts) range limits listed on the WPS for any given filler
metal and tungsten size they are using at the time.
JLab Welder Training
62
Jlab Welding Program Requirements
Filler metal selection is considered an essential variable as it relates
to the metallurgy of the weld metal placed into each weld joint.
Improper filler metal selection or use could result in premature
failure of a weld for the conditions it was intended.
JLab Welder Training
63
Jlab Welding Program Requirements
The filler metal selection is so important to the welding process; that it
will be considered a welding program violation to knowingly select or
use an improper filler metal. It is recommended that the welder verify
the correct filler metal selection with the Welding Examiner.
JLab Welder Training
64
Jlab Welding Program Requirements
Hold-Point Inspections/Examinations are a welding code and
Jlab welding program requirement. It is also a real time field
validation of the Jlab Welding Procedures Specifications (WPS),
and the front line of defense against weld defects.
JLab Welder Training
65
Jlab Welding Program Requirements
•
Hold-Point Examinations shall not be violated. Only the Jlab LevelA Welding Examiner that set the hold-point examination can wave
the hold-point examination. Blowing past a hold-point examination
will be considered a welding program violation.

New Standard Purging Requirements
I have recommended that each welder be issued or have access
to a oxygen sensor to monitor the internal purging process. A
standard maximum oxygen level percentage (PPM) will be
established that will be required to be achieved prior to starting
any welding on a CJP root & hot-pass weld on piping or tubing.
JLab Welder Training
74
Purging Requirements
The purging process is considered to be an essential variable as it
relates to the JLab Welding Procedure Specifications (WPS). Starting
welding operations on any stainless steel CJP weld joints prior to
having reached the desired oxygen purge levels (%) will be
considered a welding program violation. The welder is encouraged to
allow as much time as needed to reach purge compliance.
JLab Welder Training
75
Purging Requirements
After consultation with the Jlab Inspector, the newly established
standard purging oxygen levels will be allowed and encouraged to
be improved upon at the groups discretion. However, the ways and
means must be provided to achieve the improved oxygen levels.
