There are many types of welding, but here are four of the most common types:
1) MIG Welding (Metal Inert Gas Welding): This process involves using a wire to feed metal into the weld joint while an inert gas is used to protect the weld from oxidation and contamination.
2) TIG Welding (Tungsten Inert Gas Welding): This type of welding uses a non-consumable tungsten electrode to heat and melt the base metal, which is then joined with a filler rod.
3) Stick Welding (Shielded Metal Arc Welding): This process involves using an electrode coated in flux, which melts to protect the weld from oxidation and contamination.
4) Flux-Cored Arc Welding (FCAW): This is similar to MIG welding, but instead of using a solid wire, a hollow wire filled with flux is used to protect the weld from oxidation and contamination.
