ASME issued its first standard, Code for the Conduct of Trials of Steam Boilers, in 1884. This paper evolved into Rules for the Construction of Stationary Boilers and for Allowable Working Pressure—the first edition of ASME’s now-legendary Boiler and Pressure Vessel Code (BPVC)—issued in 1914 and published in 1915.
The American Welding Society (AWS) publishes over 240 AWS-developed codes, recommended. practices and guides which are written in accordance with American National Standards Institute (ANSI ...
When qualifying a Welding Procedure Specifica-tion (WPS) for welding base metals having different im-pact testing requirements and acceptance criteria, the following shall apply: (-a) The weld metal impact test specimens shall meet the acceptance criteria for either base metal.
Primary purpose for performance qualification. To verify the ability of an individual to execute a qualified welding procedure specification to produce a sound weld. Welders can be qualified by visual inspection and destructive testing or radiographic inspection.
This Standard covers ratings, dimensions, tolerances, marking and material requirements for socket-welding and threaded forged fittings. These fittings are designated as Class 2000, 3000, and 6000 for threaded end fittings and Class 3000, 6000, and 9000 for socket-weld end fittings.
This chapter is to introduce you to the main general welding rules contained in API 570 and ASME B31.3. API 570 is for in-service inspection of process piping and therefore most welding carried out will be repair welds, rather than welds carried out on new systems.
The Sectional Committee on the Standardization of Pipe Flanges and Fittings, B16, organized in 1920 under the procedure of the American Standards Association (ASA), appointed a subgroup of Subcommittee 3 (now Subcommittee F) to initiate the standardization of welding fittings in May 1937.
