Electron beam welding has a very precise heat affected. A metal brush is the best option to clean the muffler’s tubing, and useful as it consequently exposes the base metal. The combination of en weld polarity and faster tig weld speeds, enables the lowest possible weld joules for any metals, and this also applies when ac balance wave welds on made on aluminum weld joints.

To start welding exhaust pipes, the first thing to do is to clean the base metal for preparing it thoroughly. When i try this with the plates clamped to a piece of angle iron, the edges recede away from each other widening the gap and never forming a bond, and it does this virtually as soon as the arc starts.
