Short circuit transfer mig short arc tig and pulsed tig welding processes provide the most control over the heat to address these challenges.
How to weld thin sheet metal with a mig.
Tips for welding sheet metal with mig or tig.
Learn how to mig weld automotive sheet metal in about 5 minutes or less.
Use thin wire one big mistake we see with beginners is using welding wire that is too thick for the metal they re welding.
Keep the stick out short stickout of your mig wire is important when welding any type of metal but especially sheet.
For mig welding sheet metal it is often recommended to use an electrode wire of the smallest diameter to prevent burn through and warping.
When welding thin metal the main objective is to avoid warping burn through and excessive heat affected zones while still ensuring the weld has enough mechanical strength for the application.
For thinner gauge sheet metal like 18 or 20 gauge we suggest 023 6mm wire in your mig welder.
As a rule when mig welding sheet metal never use a body filler metal that is thicker than the base metal.
Learn why mig pulsed mig tig and pulsed tig are the ideal choices when welding sheet metal.
It is recommended that a welder should use 023 or 024 inch wire for light gauge sheet metal work.
If your welding wire is too thick it will take more heat to melt the wire than the substrate and can make it even more prone to blowing holes in the panel.
The stitch welding technique can be very powerful.
I keep it short and to the point in this welding instructional video and show how ve.
However if you are dealing with materials that are 18 gauge or thicker one should be able to use 030 inch welding wire.
