here are different types of welding particularly focused on combining different types of materials. The following are the three commonly used welding techniques.
Shielded Metal Arc Welding (SMAW)
This type of welding is sometimes called stick welding, and it uses rods or electrode sticks that are fed through a welding gun. Electricity is the primary source of power that is used to create an arc between the metal surface and the electrode to bond them utilizing melted electrodes as the filler. This type of welding is very common in construction and other heavy industries since it is used to join large pieces of metal.
Gas Metal Arc Welding (GMAW)
This is sometimes called metal inert gas (MIG) welding, and it works almost similarly to stick welding. The only difference, in this case, is that a continuous electrode wire is used to replace the sticks. MIG welding is common in the manufacturing and automotive industries. More importantly, this type of welding is neater than stick welding.
Gas Tungsten Arc Welding (GTAW)
This type of welding is also called tungsten inert gas (TIG), and it replaces consumable rod or electrode wire that is used in MIG or stick welding. Instead, it uses non-consumable tungsten implying that no filler material is required. The heat produced from the arc melts the metal surface thereby producing a bond. TIG is the neatest form of welding, but it is the slowest option. This form of welding is usually applied to delicate metal where appearances matter.
