Welding Types
Shielded metal arc welding SMAW (Stick Welding)
This type of welding uses an electric current to create an arc between a consumable electrode and the metal being welded. The heat of the arc melts the metal, and a filler material is used to join the two pieces together.
Gas metal arc welding GMAW (MIG)
Uses a wire electrode that is fed through a welding gun, along with shielding gas. The gun is used to direct the wire and gas to the weld area, and an electric current is used to create an arc.
Flux-cored arc welding FCAW
Similar to GMAW, the difference is it uses a wire electrode that is coated in flux. The flux helps to protect the weld area from contamination and can also provide additional chemical elements to the weld.
Tungsten inert gas welding (TIG)
Uses a non-consumable tungsten electrode to create an arc. The arc is used to melt a filler material, which is added to the weld area.
Submerged arc welding (SAW)
Uses a consumable electrode that is fed through a welding gun. The gun is used to direct the electrode to the weld area, and an electric current is used to create an arc. The weld area is covered with a layer of granular fusible flux, which helps to protect the weld from contamination.
Resistance weldin
This type of welding uses electric current to generate heat at the weld area by passing it through the metal being welded. The heat causes the metal to melt and form a weld.
Laser beam welding
Uses a laser beam to create a highly concentrated and precise heat source. The heat is used to melt the metal and create a weld.
Electron beam welding
This type of welding uses a high-energy electron beam to create a precise and concentrated heat source. The heat is used to melt the metal and form a weld.
