What is the AWS standard for welding symbols?

Last updated on September 25, 2022 @ 5:36 pm

AWS standard welding symbols are the most commonly used symbols in the welding industry. They are recognized by most welding equipment and are used to indicate the type of welding being performed.

There are a few different symbols used, but the most common are the T, M, and L symbols.

PRO TIP: Welding symbols are used to provide information about how a joint is to be welded. They are usually found on drawings or weld maps. While there is no official AWS standard for welding symbols, there are a few common conventions that are generally followed.

The T symbol indicates that a welding process is being performed with a torch. The M symbol indicates that a welding process is being performed with an arc welder.

The L symbol indicates that a welding process is being performed with a laser.
