Standard Welding Procedure Specifications (SWPS) covered in AWS B2.1-X-XXX Series Standards.Prequalified Welding Procedure Specifications covered in Clause 3.Qualified Welding Procedure Specifications covered in Clause 4.While I believe developing a WPS from the ground up including Procedure Qualification (PQs) based on the companies scope of work, welding capabilities, and welding process preferences, is the most economical and technically sound option, I think it is important for welding companies to know their options and have the ability to take advantage of the work AWS has put forth.ĪWS D1.1 Structural Steel Welding Code allows for three different methods to developing a code compliant WPS. ![]() ![]() Other welding codes have acknowledged these alternative methods (such as ASME adopting AWS SWPSs), but none have spent the time and resources AWS has adopting them into their welding codes. American Welding Society (AWS) has taken the lead in the welding industry with alternative methods to developing a Welding Procedure Specification (WPS).
