Welding standards

First, before starting welding, we need to prepare welding instructions or WPS for short. WPSs are written by qualified welding engineers. These engineers have taken WPS writing courses and are familiar with how to use a variety of standards.

Usually two or more different codes are used to prepare the welding instructions as needed.

Welding instructions are a set of processes that begin before welding and continue after. For example, we can mention the steps of preparing the part, selecting the method and electrode, welding status or welding amp, as well as the method of inspection and approval of welding. Usually, depending on the type of component, various standards such as ASME, AWS and API are used. In the following articles, we will examine the types of ASME, AWS and API welding standards.
