Have many different metals types that can be welded. It is important to know how to weld specific welding metal types so that you need the correct welding equipment to properly get the job done. Following 3 kinds of Common Welding Metals 1.Welding Metals type: Aluminum To Welding aluminum parts require high power welding and very clean oxide-free surfaces. Cleaning a surface to be oxide-free can add extra cost to the welding project. But will make the welds cleaner and easier to deal with, keeping the metal from pooling and having surface tension when it is melted. Use a tungsten inert gas welder and the welding flame should be set to blue. Which is the hottest flame to melt the metal and make it possible to weld. It is also a good idea to preheat the aluminum before actually welding on it because this makes it much easier to weld. 2. Welding Metals type: Steel Different steel type require different welding tools and techniques, assuming it can be welded in the fir
