BS 4872-1:1982

This standard BS 4872-1:1982 Specification for approval testing of welders when welding procedure approval is not required is classified in these ICS categories:

• 25.160.01 Welding, brazing and soldering in general

This Part of this British Standard 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.

NOTE Users of this standard should be aware that some steels may require special treatment during welding if defects, such as cracks and porosity, are to be avoided. This may entail careful selection of welding consumables, their drying or conditioning prior to use, applying preheat and/or post-weld heat treatment and control of welding heat input. When such a steel is encountered consideration should be given to the provision of a detailed welding procedure with corresponding approval of the procedure and welders in accordance with the companion standards mentioned in the foreword.

Covers the approval testing of welders for manual or semi-automatic fusion welding of ferritic or austenitic stainless steels when welding procedure approval is not required. There is a choice of 9 test welds covering sheet, plate and pipe, with requirements for examination and testing.
