摘要

The purpose of this series is to outline to NON DESTRUCTIVE TESTING TECHNICIANS the basics of the common welding processes. It is important that NDT technicians involved in the inspection of welds have a basic understanding of the popular welding processes. Welding is an extremely interesting and varied process, and there are a variety of different welding processes in use today. Some of the more popular welding processes in use in industry are SMAW (stick), GMAW (MIG). FCAW. (FLUX CORED)), GTAW (TIG) SAW (SUB ARC).
