Best gas for welding sheet metal.

So the question is. There are other mixtures that work well depending on the type of welding that will be done. Welding of carbon steel can be done with carbon dioxide alone and it produces the deepest penetration the most smoke and the roughest weld. Why would i ever want to gas weld anything.

The most widely used mixture is called c25 and that is 25 carbon dioxide and 75 argon gas. For these types of materials a tri gas mixture is recommended which consists of 90 helium 8 argon and 2 co2. Tips for welding sheet metal with mig or tig. While wire feed welding sheet metal go for short bursts of welding instead of a going on a long bead.

Forney 30705 e7018 welding rod. For sheet metal i use ine welding wire and it is just as good as their flux cored wire if you want you can grab one here. If you will use spray transfer then got with not less than 20 carbon dioxide. Because it will have you a lot more control over.

Always use the smallest wire diameter possible since smaller wires take less heat to melt and heat the metal less. Oxy fuel or oxy acetylene welding are gas welding procedures that were invented in the early 1900 s. Check out our project page for diy welding projects. Tig welding sheet metal.

Short bursts or tacks will help. Try going for a wire of 023 inches when welding sheet metal. If using short circuit transfer in thinner parts using 100 is acceptable but will generate more spatter. The high carbon dioxide content does a good job of welding through the zinc coating.

Ditch a 1 8 inch tungsten electrode for something much smaller like 1 16 inch tungsten. Carbon steel and 18 ga. How thin is this metal. Mig welding sheet metal.
