BS 4872-1:1982

Specification for Approval testing of welders when welding procedure approval is not required - Part 1: Fusion welding of steel

Requirements for the approval testing of welders to be engaged on manual or semi automatic fusion welding of ferritic steel or austenitic stainless steel fabrications.

This British Standard, a part of the BS 4872 series, specifies requirements for the approval testing of welders to be engaged on the manual or semi-automatic fusion welding of those ferritic steel or austenitic stainless steel fabrications for which the welding procedure does not itself have to be approved.

The welder is provided with written instructions and information covering the following details:

a) parent metal (ferritic steel or austenitic stainless steel);

b) welding process and polarity;

c) welding consumables (electrode or filler material specification, type of flux, shielding gas composition);

d) welding position;

e) metal thickness and, for pipe, the outside diameter or dimension;

f) joint type, with sketch of weld preparation;

g) weld dimensions required.

Other factors are left to the choice of the welder but the relevant details are recorded.

This British Standard supersedes BS 4872-1:1972 which is withdrawn.
