    Abstract - (Show below) - (Hide below)

    Describes essential requirements, ranges of approval, test conditions, acceptance requirements and certification for the approval testing of welder performance for the welding of aluminium. During the approval test the welder should be required to show adequate practical experience and job knowledge. Applicable when the welder's approval testing is required by the purchaser, inspection authorities or other organizations. Applies to the approval testing of welders for the fusion welding of aluminium using a gas shield. The welding processes referred to include those fusion welding processes which are designated as manual or partly mechanized welding. It does not cover fully mechanized and fully automatic processes.
