This Malaysian Standard specifies specifies requirements for the qualification testing of welding procedures for the arc welding of tube to tube-plate joints in metallic materials by manual, partly mechanized, mechanized or automatic processes. Qualification by tube to tube-plate joint tests can be used for all joints even if they are fully loaded or only seal welded as required in application standards. This Malaysian Standard applies to fusion welding of metallic materials for tube to tube-plate joints with gap. This standard does not apply to tube-sheets with forged end connections with welded tubes (external/internal bore welds). For welding of tube to tube-plate joints without gap welding procedure test should be defined in the specification. For other applications and/or requirements the standard can be used if required by the specification. Repair welding should be considered in the welding procedure test.
