The principle of gas welding is to heat two pieces of metal to their melting point or very close to it using a gas flame, then perform an action that causes them to fuse together. This action is typically the addition of more metal, but some metals can be welded together by heating them to the point where they become plastic, then laying one atop the other and beating the heck out of them with a hammer until they fuse into one piece.
Larger in Gas Welding. In all arc processes the HAZ is concentrated in a couple inches around your bead. In gas welding it can be double or triple that size.

Some methods are used: - electron beam welding - laser beam welding - gas wolfram arc welding - gas metal arc welding - resistence welding - brazing
Stick welding
argon gas
The welding operation is stopped by moving the welding torch away from the workpiece to break the electrical circuit and extinguish the welding arc. Additionally, turning off the welding power source or releasing the welding trigger can also stop the welding operation.
One limitation of gas welding is the limited range of materials for which it is suitable, as it may not work well with certain metals or thicknesses. Additionally, gas welding can result in slower welding speeds compared to other methods like arc welding. Maintaining the proper gas pressure and flow during gas welding can also be challenging.
