Specifies requirements for fusion welding in the fabrication and rectification of steel castings, primarily to AS 2074. It includes requirements for the welding consumables and equipments, qualification of welding procedures, qualification of welders, weld preparation, preheating, and postweld heat treatment.

This Standard specifies requirements for the fusion welding of steel casting where it is used-(a) to rectify a casting as part of the normal production process; (b) to rectify a casting that has been in service; and (c) for the joining together of steel castings by fusion welding, where the subsections of the final fabrication are designed for that purpose or where welding is introduced at the foundry planning stage.This Standard covers the manual metal-arc, gas-shielded, self-shielded, and submerged-arc welding of the materials given in Table 2.1 and Table 2.2, but additional guidance for other processes has been given in some clauses.Although this Standard does not directly cover the welding of steel castings to wrought steels, it may beused as a guide for the fabrication by joining of these forms of steel involving similar and dissimilar metals.
