Welding gas can refer to two things. In torch welding, it is either a fuel gas such as acetylene or MAPP or oxygen, and in arc welding (MIG, TIG, etc...) it refers to any of the inert gases such as carbon dioxide or argon that is pumped over the weld pool to protect it from atmospheric contaminants.
Gas Tungsten Arc Welding Gas Metal Arc Welding Flux Cored Arc Welding
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
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.
