AWS B2.1: 2005 Specification for Welding Procedure and Performance Qualification
276 стр.
An American National Standard
Approved by the American National Standards Institute
November 5, 2004
This specification provides requirements for the qualification of welding procedures. It also provides requirements for the performance qualification of welders and welding operators. This specification is intended for use where referenced by a product or fabrication code, specification, contract document, or inteal documents such as quality control or quality assurance manuals. The requirements imposed by the Referencing Document (see 1.3.2 Supplemental Definitions) supersede the requirements of this specification. This specification is intended for use with the following welding processes:
OFW = Oxyfuel Gas Welding
SMAW = Shielded Metal Arc Welding
GTAW = Gas Tungsten Arc Welding
SAW = Submerged Arc Welding
GMAW = Gas Metal Arc Welding
FCAW = Flux Cored Arc Welding
PAW = Plasma Arc Welding
ESW = Electroslag Welding
EGW = Electrogas Welding
EBW = Electron Beam Welding
LBW = Laser Beam Welding
SW = Stud Arc Welding
Appropriate metric conversions are included for all dimensions. However, the customary units are standard units, and the metric units are for information only. It is intended that inspection of qualification test welds is to be accepted based on the U.S. customary dimensions, not on the metric conversion values of these dimensions.
