Standard Welding Procedure Specifications (SWPS) : Resources : Standards : American Welding SocietyCommittees and subcommittees comprising volunteer workers interested in furthering the quality and efficiency of the welding industry work together to develop these codes. In some areas both are the same. In others they are very different. ASME is specifically for welder and welding procedure qualification. Some work contracts require that a specific code be used for qualifying the welders, but in many cases either code is sufficient. If the job consists totally of structural welding and the contract specifies the AWS Structural Code, then that is the code that must be used for all aspects of the job. If the job is related to ductwork associated with a boiler, the contract usually allows qualification with either code.

Welding codes and standards address all aspects of design and fabrication of welded components, including welding procedure specifications, quality control and quality assurance during welding and necessary welding skills for a given welding procedure in all industry sectors. The relevant code is often specified by the end user or client as a contractual agreement in order to control the characteristics of the welded components that may affect the service requirements.

Painting to an appropriate specification will significantly extend the period to the onset of corrosion but the durability of the paint finish is largely dependent on the quality of the surface preparation. In others they are very different.
Published on December 12, December 1, Four groups set the foundation for the codes. Each group sets and adapts codes that pertain to their area of interest. The most commonly used codes are from the AWS D1. AWS is for both welder and welding procedure qualification including inspection, erection and fabrication.
