Specification for approval testing of welders when welding procedure approval is not required - TIG or MIG welding of aluminium and its alloys shop-only Design engineers of burrs1 Scope This British Standard specifies requirements for the approval testing of welders to be engaged on the TIG or MIG welding of those aluminium and aluminium alloy fabrications for which the welding procedure itself does not 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, e. g. with regard to
