Welding Procedure Specifications (WPSs) - National Certified Pipe …
Procedure Specifications For Pipe Welding/Brazing. The Procedure Specifications listed below are the results of research. They have been developed by members or through technical representatives of the members of NCPWB and the costs thereof have been defrayed through the dues and contributions of members of NCPWB.
submit welding procedure specifications to the CWB for acceptance. A welding procedure specification (WPS) sets broad guidelines for the shop and field welding practice of the fabricator for each anticipated combination of essential variables.
2000年7月20日 · This document presents recommended practices for welding mild steel pipe. It is intended to cover piping systems such as for low pressure heating, air conditioning, refrigeration, water supplies, as well as some gas or chemical systems.
Weld After Backfill is a sequence used to improve overall installation rate for steel pipe. Pipe is laid and welded outside (if required). Joint coating is applied, usually a shrink sleeve or mortar diaper. Pipe is backfilled. The inside weld is made later. Issue: Welding subcontractor or welders are inexperienced production welding of steel pipe.
These General Welding Guidelines are intended to provide background information and supplementary instructions to contractors and their welders who are using National Certified Pipe Welding Bureau Welding Procedures Specifications (WPSs). This document is divided into two sections: Mandatory Practices and Recommended Practices.
Pipe Welding Tutorial
Pipe welding makes connecting pipe much easier than threading it. It's also less costly. Plus, you'll get better flow through pipe that has been welded together versus using connecting devices and other equipment for joining pipe. The most common welding procedure for pipe is stick welding (SMAW).
“ The art and science of joining metals by using the intrinsic adhesive and cohesive forces of attraction that exist within metals”. When Did Welding Begin? Temperature Of The Sun? Temperature Of The Arc? What Is a Welding Procedure? Why Have Welding Procedures? Who Should Have Welding Procedures? What Information Should Procedures Contain?
What is a Welding Procedure? A procedure is the description of the technique adopted to perform quality welding as required by the applicable code. Through the years, standards have been established for pipe dimensions, flange and fitting dimensions or various pressures, pipe thread dimensions, and pitch.
