IS 7318 : Part 1 : 1974 : Approval Test for Welders When Welding Procedure Approval is Not Required - Part I : Fusion welding of Steel

1. SCOPE

1.1 This standard specifies requirements for the approval testing of welders to be engaged on the manual or semi-automatic fusion welding of those structural or austenitic steel fabrications for which the welding procedure does not itself have to be approved.

NOTE - This link to the non-mandatory approval of the welding procedure will result in the use of this standard becoming defined more closely in respect of the particular fabrication, for example, with regard to material, thickness, joint configuration.

1.2 This standard is applicable to the following manual and semi-automatic welding processes:

a) Manual-metal-arc,

b) Inert-gas tungsten arc (TIG),

c) Gas-metal arc (MIG or CO,),

d) Submerged-arc, and

e) Gas welding.
