Tig welding machines. â More specialized than mig welders tig machines are used for precision work and can weld more types of metal than any other process. Metals suitable to tig weld are stainless steel, mild steel, aluminum,copper, bronze, brass, gold, magnesium, chromoly, and nickel alloys.
There are many different types of electrodes used in the shielded metal arc welding, (SMAW) process. The intent of this guide is to help with the identification and selection of these electrodes. Arc welding electrodes are identified using the A.W.S, (American Welding Society) numbering system and are made in sizes from 1/16 to 5/16 . An example would be a welding rod identified as an 1/8. E6011 electrode. The electrode is 1/8 in diameter. The E stands for arc welding electrode. Next will be either a 4 or 5 digit number stamped on the electrode.
