When welding exhaust systems, weldors will typically need to know how to weld both "tube to tube" butt welds, as well as "tube to plate" fillet welds. Today we are going to show you how to certify for exhaust applications using AWS's D17.1 specification for fusion welding of aerospace applications.
1G Position
The first weld we are going to attempt is a tube to tube butt weld in the 1G position. The 1G position is officially identified as, "The position of a pipe joint in which the axis of the pipe is approximately horizontal, and welding is performed in the flat position by rotating the pipe".

After the 1G weld is completed we will attempt to do a 2F "tube to plate" fillet weld. The 2F position is officially identified as, "The position in which welding is performed on the upper side of an approximately horizontal surface and against an approximately vertical suface and the pipe is not rotated during welding.

This time was no exception. When we were filming at one of our local auto body shops, we had someone come by and ask us if we could help him with a project.

Often times we get projects from friends or viewers of the show asking us to help them out with a weld, but they don't know what the material is. If we know the part's manufacturer or we can look up a part number, we can usually find an exact material. However, there are many times when the material or part is generic or so old that there is no information that we can find.

This is when we have to determine the type of metal we are about to weld on. There are a few simple ways you can narrow down material's alloy with nothing more than some magnets, a grinder and some basic senses.
