Welding Different Gauge Metals Together. There is a range of different uses for gas in welding. I was hoping to get some tips or techniques on MIG welding metals of different thicknesses togetherLike welding 18 plate to car sheet metal ya know very Monster Garage-esqueWhat do you more experienced guysgals do.
Before welding I set my inverter welder to 150 amps output pulse rate at 200 and clamped 18 x 34 copper bars behind the sheet metal. Welding is the process by which two pieces of metal can be joined together. To weld sheet metal with solid wires use electrode positive EP or reverse polarity.
Making sure that the welding pool stays clean below the seam this is known as purging for.
There are four basic types of welding. However nickel is soluble with both of them and so can be used as the buttering layer either as a whole piece of nickel or as smaller nickel deposits on the steel surface. MIG TIG flux-cored and stick. It is recommended that a welder should use023- or024-inch wire for light gauge sheet metal work.
