Welding Wire For Automotive Sheet Metal

With portable design and wide applications the suncoo features a variable feed speed controls and a rotary knob to easily adjust the current flow and wire.

Welding wire for automotive sheet metal.

Ditch a 1 8 inch tungsten electrode for something much smaller like 1 16 inch tungsten. So you can keep the other hand free for manipulating your materials and other tools. Mig or metal inert gas welding aka gas metal arc welding or gmaw also uses a gas shield and filler material however in this case the filler is a wire fed directly through the welder. This chapter concentrates on some of the fundamentals of welding sheetmetal sections and on a few ploys that that may make this type of welding easier for you to perform while producing superior results.

That makes this a one handed process. Holding the tip too far from the surface will cause the wire to have to come out too far to touch the metal. As i will prefer to call it the best mig welder for sheet metal it uses a flux core wire and self release metal inert gas while welding preventing the oxidation of the welded area. When the material is 18 gauge and thicker you may be able to use a 030 inch wire.

It s recommended to use a 023 or 024 inch wire for most light gauge sheet metal work. Mig welding is the preferred method for most automotive bodywork and since sheet metal is the thinnest of metals a large expensive mig unit is usually not required. For thinner gauge sheet metal like 18 or 20 gauge we suggest 023 6mm wire in your mig welder. The majority of the sheet metal welding i ve done was with a 90 amp 110 volt welder.

To weld mild steel choose an american welding society classification wire such as er70s 6 which has a weld puddle that wets out nicely. Automotive sheetmetal and structural welding are vast topics and it is not possible to give them anything approaching complete coverage here.
