Standard Welding Procedure Specifications (SWPS) : Resources : Standards : American Welding SocietyTo be referenced as a supporting document for an SWPS, a PQR received from an industry or government agency must be qualified and documented in accordance with one of the nationally recognized codes or specifications such as AWS D1. It is the policy of the AWS B2 Committee that the range of conditions and variables listed for an SWPS be more restrictive than permitted by application of the full range of conditions and variables allowed by the B2. The purpose of this policy is to restrict the WPS to a high probability of successful application by all users. In judging the extent of such restriction, the Committee is guided by the number and scope of the supporting PQRs, including the specific material, thickness and value for each welding variable used for the development of the PQR, and by known fabrication experience. The minimum number of supporting PQRs required by the Committee is two, but is usually in the range of two to fifty, the specific minimum number being a Committee decision for each SWPS. The demand for most trades is strong and getting stronger.

Welding Codes, Standards, and Specifications. Jeffrey D. Welder's bible interprets all four major welding codes Get instant, accurate answers to any question that arises during the design, construction and inspection stages of all your welding projects. This first-ever one-stop guide to the welding codes and standards from the AWS, UBC, AISC, BOCA and many others makes it a breeze to locate codes on every aspect of welding: piping; sheet metal; structural beams; fabrication; bolts and joints; you name it. Packed with useful see-how-to-do-it illustrations, this alphabetized and extensively cross-referenced resource lets you instantly locate the welding code details you need in one of the book's six convenient sections--general information, structural steel, tables, high strength bolts, reinforcing steel and sheet steel--so you can easily find what you need and get back to work fast. Section B Structural Steel.
TWI's welding engineers have extensive experience operating to international codes, standards, regulations and specifications from procedure qualification for original fabrication to quality control and quality assurance during welding to repair process development in all industry sectors. Our welding engineers can provide an expert opinion on all the major welding and fabrication standards:. Our welding engineers are qualified to work according to the main international welding standards, many of them are involved in the standardisation committees and their skills have often proven crucial in providing clarification on the intent of clauses within welding standards.

Welding codes are very important to the welding engineer because they govern and guide welding activities to ensure safety, reliability, and quality of the applicable weldment or welded structure. Codes and specifications are typically incorporated in the contract for producing a welded fabrication, and therefore, establish important information such as inspection methods and acceptance criteria for a weld, or methods for qualifying welders and weld procedures. The AWS D1. There are three very important records or documents that verify if welding quality is being maintained: the procedure qualification record PQR , the welding procedure specification WPS , and the welder performance qualification WPQ.
All sections contain welding specifications, however most relevant information is contained in the following:. API maintains over standards covering the oil and gas field. Standards Australia is the body responsible for the development, maintenance and publication of Australian Standards.
