Welding personnel. Approval testing of welding operators for fusion welding and resistance weld setters for fully mechanized and automatic welding of metallic materials Ingestion-build-83346 Stress-relief heat treatments before coatingThis European Standard specifies requirements for the approval of welding operators for fusion welding and resistance weld setters for fully mechanized and automatic welding processes of metallic materials. Only welding operators resistance weld setters, responsible for setting up and or adjustment during welding have to be approved. Personnel exclusively performing the programming of the welding unit or operation of the welding unit do not require
