Some of the names used to refer to oxyacetylene welding (OAW) include gas
welding and torch welding.
Shielded metal arc welding (SMAW) is often called stick welding, rod welding,
or just welding.
Welding is defined as “a joining process that produces coalescence of materials
by heating them to the welding temperature, with or without the application of
pressure or by the application of pressure alone, and with or without the use of
filler metal.”
Very little in our modern world is not produced using some type of welding
process.
Welding processes differ greatly in the manner in which heat, pressure, or both
heat and pressure are applied and in the type of equipment used.
In OF welding and TB a high-temperature flame is produced at the torch tip by
burning oxygen and a fuel gas.
Shielded metal arc welding (SMAW) uses a consumable stick electrode that
conducts the welding current from the electrode holder to the work, and as the
arc melts the end of the electrode away, it becomes part of the weld metal.
Gas tungsten arc welding (GTAW) uses a nonconsumable electrode made of
tungsten.
Gas metal arc welding (GMAW) uses a solid electrode wire that is continuously
fed from a spool, through the welding cable assembly, and out through the gun.
Flux cored arc welding (FCAW) uses a flux core electrode wire that is
continuously fed from a spool, through the welding cable assembly, and out
through the gun.
There are a number of thermal cutting processes such as oxyfuel cutting (OFC)
and plasma arc cutting (PAC).
Oxyfuel gas cutting uses the high-temperature flame to heat the surface of a
piece of steel to a point where a forceful stream of oxygen flowing out a center
hole in the tip causes the hot steel to burn away, leaving a gap or cut.
Plasma arc cutting (PAC) uses a stiff, highly ionized, extremely hot column of
gas to almost instantly vaporize the metal being cut.
In a manual operation the welder is required to manipulate the entire process.
In a semiautomatic operation filler metal is added automatically, and all other
manipulation is done manually by the welder.
In an automatic operation a machine has been programmed to perform
operations repeatedly without interaction of the operator.
Welder assemblers, or welder fitters, position all the parts in their proper places
and make them ready for the tack welders.
Welding inspectors are often required to hold a special certification such as the
one supervised by the American Welding Society known as Certified Welding
Inspector (CWI).
To become a skilled welder, both welding school and on-the-job experience are
required.
In addition to welding skills, an entry-level welder must possess workplace
skills such as teamwork, leadership, integrity, honesty, organizational skills,
time management, understand the importance of workplace diversity, and the
Equal Employment Opportunity law.

Column A
Beginners in welding who have no training often start in manual welding production
jobs that require minimum skill.
Many more skilled welders will be needed for maintenance and repair work in the
expanding metalworking industries.
Before being assigned a job where service requirements of the weld are critical,
welders usually must pass a certification test given by an employer.
Job related personal skills are important because people are hired based on their
welding skills but too often they may be later fired for not having good job related
personal skills.
Each individual working on a project has to work efficiently and effectively with the
other team members.
An example of a detailed written communication is a Welding Procedure Specification.
Each welding project may have unique challenges that must be overcome in order to
complete the task or work, requiring welder to have the ability to adapt their thinking
to solve different and unique problems.
Scanning is a reading technique where you quickly look over printed material to gain
an overview while looking for a specific piece of information.
It is important that you be punctual for work and arrive at least 15 or 20 minutes before
work begins so that you can be ready to start work promptly.
Failing to notify the company or accruing excessive absences can result in your
termination.
After you graduate or complete your welding program, you need to continue to learn.
The AWS SENSE certifications have gained widespread acceptance by the industry and
they allow welders to demonstrate their skills on a standard welding test.
The first three modules of the Entry Level Welder SENSE program relate to practical
knowledge that is common to all areas of welding and that welders must have to
succeed in the welding field.
Modules 4 through 7 relate to welding performance (skills) in each of the major
welding processes.
Module 8, Thermal Cutting Principles and Practices, is divided into four units, with
each covering different types of thermal cutting.
Module 9 covers two main areas of inspection and testing.
Level II Advanced Welding Qualifications are divided into two sections: Knowledge
Subjects, which require students to be tested, and Performance Testing, which requires
students to pass a welding skill test.
Each year SkillsUSA sponsors a series of welding skill competitions for its student
members.
Often as you make a weld, it will be necessary for you to make changes in your
equipment settings or your technique to ensure you are making an acceptable weld.
Many calculators today have built-in standard and metric conversions; of course,
it is a good idea to know how to make these conversions with and without
these aids
