There are many kinds of welding such as Mig welder, Tig welder, Arc welder and many others. You can also find few resistances welding such as spot welding. Spot welding is mostly used for welding sheet metal fabricators. It is a process of touching the surface of metals by heat which is joined with another metal where the heat is generated from electric flow to resistance.

These welding are one of the oldest and were known as projection welding. These are very useful while welding for thin foils. These are energy efficient and also can weld in high speed. This welding equipment has an ease of automation and are very easy to handle. These are used for many kinds of applicators such as automobile industry, orthodontist and many other industries. You can spot weld the aluminum alloy with the use of powerful welding transformer. This is very useful for welding the sheet metal for cars and can weld automatic with the help of robot. These are also utilized for joining the cells of batteries with nickel straps. The battery might get hot while soldering but nothing will happen if you use spot welding.
