    Abstract - (Show below) - (Hide below)

    Specifies requirements necessary for the granting of certificates to persons engaged in the operation of various welding processes used in the manufacture of boilers, pressure vessels and associated piping, as well as other applications requiring a prescribed standard in the theory and practice of welding.

    Scope - (Show below) - (Hide below)

    This Standard specifies the requirements necessary for the granting of certificates to persons engaged in the operation of various welding processes used in the manufacture of pressure equipment such as boilers, pressure vessels and associated piping as defined in AS 1200, as well as other applications requiring a prescribed standard in the theory and practice of welding.Certification in welding is related primarily to basic welding techniques and processes and not to the parent metal of the joint.Welder certification should not be confused with welder qualification (see Clauses 1.5.45 and 1.5.46). The requirements for welder qualifications are specified in the appropriate application Standards.
