From Wikipedia, the free encyclopedia. Welder certification, (also known as welder qualification) is a process which examines and documents a welder's capability to create welds of acceptable quality following a well defined welding procedure.elder certification is based on specially designed tests to determine a welder 's skill and ability to deposit sound weld metal.
Many trade and vocational schools offer welding courses as well, covering both traditional methods and newer technologies. AWS certification doesn't favor either approach. Welding certification is a pure meritocracy: Show up at the test site, prove you can do the job to appropriate standards, and you'll receive certification. The certification is good for one year but will be automatically renewed as long as you work in the same type of welding and submit documentary proof at six-month intervals.
