BS 4677 is a British Standard that discusses arc welding.
BS 4677 specifies requirements for both shop and site arc welding, using manual, semi-automatic, automatic, and mechanized welding processes, or combinations of these joints in austenitic stainless steel pipework intended to carry fluids.
In addition to the definitive requirements, it also requires the items detailed in clause 2 to be documented. For compliance with BS 4677, both the definitive requirements and the documented items have to be satisfied.
Note: The titles of the publication referred to in BS 4677 are listed on the inside back cover.
BS 4677 on arc welding of austenitic stainless steel pipework is useful for industries such as:
BS 4677 can also be beneficial to:
Austenitic stainless steels are the most weldable stainless steel in current industrial practices. This brand of stainless steel can be welded without the use of any heat treatment whatsoever.
BS 4677 provides you with guidance on the conditions of pipes to be considered before welding, gases for shielding and purging, and best industry equipment requirements and welding processes requirements for austenitic stainless steel pipework.
BS 4677 specifies the information and requirements to be agreed upon and to be documented between purchaser and manufacturer.
If you are manufacturer, complying with best-industry requirements specified in BS 4677 can provide you with standardization and can ensure your austenitic stainless steel pipework components are fit for purpose, such that the operational and functional integrity of the overall pipework system is maintained.
