ASME-qualified welders demonstrate proven competency in specific welding processes, positions, and materials through rigorous performance testing. These qualifications, documented in Welder Performance Qualification (WPQ) records, ensure that only skilled craftspeople perform critical code welds.

Maintaining a qualified welder workforce requires ongoing training, periodic requalification, and careful tracking of qualification variables. This tag covers welder qualification requirements, continuity maintenance, troubleshooting qualification challenges, and developing welder skills for advanced code applications.
