WQTR: The WQTR or welder qualification test record describes the results of a test to determine if a welder is qualified to weld to a certain welding procedure specification.

It is a record of testing results for any welds created in accordance with the welding procedure specification (WPS).

PQR: The PQR is the procedure qualification report.

It also lists important code requirements, techniques, parameters and welding materials. It shows the welder an overall direction, shows the welding materials and joint design.

WPS: A WPS is the welding procedure specification.The result is growth in the profession when it comes to skill, quality, and welder efficiency. They have the effect of improving welder skills, equipment, and processes. The purpose of each of the welding codes is to have a uniform way to approach welding that reflects the best practices developed and proven to work overtime.

welding codes are written for welders, engineers, erectors, fabricators and inspectors that work with or around welded steel structures Why Welding Codes Exist Often a work contract will specify the correct code. The list below is the codes that are used to define requirements for the most common welding processes. The codes established by these organizations are then adopted by others such as the Department of Defense.Ĭodes are also recognized by the American National Standards Institute (ANSI).

American Society for Non-Destructive Testing (ASNT).

American Society of Mechanical Engineers (ASME).

The difference between ASME and AWS is that ASME is for welding procedure and welder qualification.ĪWS is for both welder and welding procedure qualification including inspection, erection and fabrication.Ĭontracts may specify one or the other code. The most commonly used codes are from the AWS (D1.1) and ASME (Section IX). The welds may be produced by position or roll welding or by a combination of position and roll welding.Welding codes are developed by a variety of organizations to set requirements for:įour groups set the foundation for the codes.Įach group sets and adapts codes that pertain to their area of interest.

The welding may be done by a shielded metal-arc welding, submerged arc welding, gas tungsten-arc welding, gas metal-arc welding, flux-cored arc welding, plasma arc welding, oxyacetylene welding, or flash butt welding process or by a combination of these processes using a manual, semiautomatic, mechanized, or automatic welding technique or a combination of these techniques. It applies to both new construction and in-service welding.

This standard covers the gas and arc welding of butt, fillet, and socket welds in carbon and low-alloy steel piping used in the compression, pumping, and transmission of crude petroleum, petroleum products, fuel gases, carbon dioxide, nitrogen and, where applicable, covers welding on distribution systems.
