Best Type Of Welding For Sheet Metal

The spot welding process is one of the oldest welding methods used.

Best type of welding for sheet metal.

The best two electrodes for welding auto body sheet metal is either ceriated tungsten or thoriated tungsten. Ditch a 1 8 inch tungsten electrode for something much smaller like 1 16 inch tungsten. Holding the tip too far from the surface will cause the wire to have to come out too far to touch the metal. Butt welded panels withstand stress better than any other type of weld joint.

The ration of thickness should not exceed 3 1mm. This machine is comparable to tig machines twice its price and we highly recommend it. The best all around welding rod would be the 6011 especially for the diy er and hobbyist. Arc welding is best used on heavy metals of size 4mm and above and is used in repairing heavy equipment steel erection and pipeline welding as well as in the manufacturing and construction industry.

Keep the stick out short stickout of your mig wire is important when welding any type of metal but especially sheet metal. The best tig machine for sheet metal welding is the primeweld tig225x 225 amp igbt ac dc tig welder. It is a fast fill freeze rod runs on both ac dc and handles dirty contaminated jobs better than other electrodes. For mig welding sheet metal it is often recommended to use an electrode wire of the smallest diameter to prevent burn through and warping.

With 3 32 and 1 8 size rods on hand the 6011 will get the majority of your jobs done. Making a patch panel take some time to make your patch a perfect fit. Spot welding is usually used to join a panel of overlapping sheet metal parts that are usually 3mm thick. Learn why mig pulsed mig tig and pulsed tig are the ideal choices when welding sheet metal.

Its primary usage is in welding auto body and sheet metal. For thinner gauge sheet metal like 18 or 20 gauge we suggest 023 6mm wire in your mig welder. 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. The main reason to use a smaller diameter wire is that it takes less heat for melting and hence the metal around the weld is not heated to a very great extent.

The best way to weld sheet metal panels together is by butt welding which is joining them side by side see picture below.
