22 Inspector Duties

Before welding begins, the inspector checks drawings, WPSs, and performance qualifications; establishes hold points; develops a documentation plan; reviews material documentation; examines base metals; verifies fit-up and joint alignment; and reviews welding consumable requirements.

During welding, the inspector checks preheat and inter-pass temperatures, verifies conformance to the WPSs, examines the root pass, and examines weld layers. After welding, the inspector examines the surface quality of the finished weld and verifies dimensional accuracy.
