is absolutely one of the hardest trades there is when it comes to proving yourself.
There are codes, specifications, and procedures that have to be mastered, then
proven time after time. Certification papers make you a "certified"
welder. They show you've passed a welding test. (The Importance
of Weld Tests )
a certified welder means you can pass a test, but it does not necessarily mean
you are a good hand. Someone who goes to welding school may spend hours doing
nothing but welding test plates. If they have any talent at all, and with all
that practice, they will probably pass the code to become certified. But it's
a whole different story out on the job site. Welding in a booth at school ain't
the same as standing on a 2" wide beam, 20 floors up in the air, with the
wind blowing like crazy.
on Discounted Welding Rod Ovens
a journeyman Iron Worker, have 2 degrees, and have been in the welding field for
over 25 years, 13 of them teaching. Yet I could go to the union hall, get sent
to a job with a greenhorn whose been welding just a couple of years, and still
both of us have to take a weld test!
done exactly that, walked into the test shack at a coal-fired powerhouse with
my certification papers like I owned the place. My certification paper was from
the American Welding Society code allowing me to weld in all positions, all thicknesses,
and were good for both mild steel and stainless. When I showed them to the guy
in charge of testing he said
"Hey, that's really impressive, you're
certified. Now grab some plates and go test!"
are several different codes which are usually nationally established. Three of
the top organizations establishing welding codes for welder certification are
the American Welding Society (AWS), the American Petroleum Institute (API), and
the American Society of Mechanical Engineers (ASME).
The American Welding Society is primarily concerned with structural applications
such as high-rise office buildings, power houses, dams, etc.
The American Petroleum Institute is just what the title 'sez. It regulates the
welding on all petroleum vessels such as oil storage tanks, carbon dioxide spheres
and the like.
ASME - The American Society of Mechanical Engineers regulates welding on pressure vessels
such as steam drums and boilers.
a welder to become certified with one of these agencies, he or she will follow
the specific code set forth in the organization's Welding Procedure Specifications
or WPS. Even though these organizations have different standards, they are very
similar in the tests they give for welding certifications as well as their set
welding certification papers from the AWS does not necessarily mean you can use
them for a job using the ASME code. The more certifications a welder has, the
better because in life every feather you put in your cap will help. However, even
with all the certifications in the world, depending on the job, you'll be proving
yourself all over again!
