Laser Beam Welding Laser welding employs a highly concentrated beam of light to melt the metal. This method is favored for its versatility, efficiency, and the relative affordability of the equipment and consumables.

Shielded Metal Arc Welding (SMAW) Also known as stick welding, SMAW is the quintessential archetype of welding. Gas Metal Arc Welding (GMAW/MIG) Gas Metal Arc Welding, commonly called MIG (Metal Inert Gas), feeds a continuous wire electrode through a welding gun while an inert shielding gas protects the arc.
To prevent this molten pool from reacting with atmospheric oxygen and nitrogen—which leads to weak, brittle welds—a protective shielding mechanism is employed. This shielding can be a gas blanket, a flux coating on the electrode, or a combination of both.

Gas Tungsten Arc Welding (GTAW/TIG) TIG welding uses a non-consumable tungsten electrode to create the arc, while the operator manually feeds a separate filler rod into the weld pool. An inert gas, typically argon, shields the tungsten, the molten metal, and the hot electrode.
