Welder Qualification Testing
Welder, welding operator, and tack welder qualification tests determine the ability of those tested to produce acceptably sound welds with the process, materials, and procedure called for in the test. Qualification tests are not intended to be used as a guide for welding during actual construction, but rather to assess whether an individual has a certain minimum level of skill. The test does not determine what an individual normally will or can do in production. For this reason, complete reliance should not be placed on qualification testing of welders. The quality of all production welds should be determined by inspection during and following completion of the actual welding.
Various codes (such as American Welding Society (AWS) D1.1 Structural Welding Code and ASME Boiler and Pressure Vessel code Section IX), specifications, and governing rules generally prescribe similar though frequently somewhat different methods or details for qualifying welders, welding operators, and tackers. The applicable or required standard should be consulted for specific details and requirements.
