scope:

This International Standard specifies requirements for 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 the 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 need any particular approval.

This International Standard is applicable when approval testing of operators/resistance weld setters is required by the contract or by the application standard.

This International Standard does not apply to welding operators in resistance welding or under hyperbaric conditions.
