The most common gas welding process is oxyfuel welding, also known as oxyacetylene welding.

This is more like gas welding as a process, but with a different heat source.
3.
A filter suitable for gas welding, for instance, should not be used for arc welding.
4.
With the invention of electrical and gas welding methods during the Industrial Revolution, manual forge-welding has been largely replaced, although automated forge-welding is a common manufacturing process.
5.
Many gas welding processes, such as lead burning, are typically autogenous and a separate wire filler rod of the same metal is only added if there is a gap to fill.

Meredith named the process Heliarc because it used a tungsten electrode arc and helium as a shielding gas, but it is often referred to as tungsten inert gas welding ( TIG ).

Gas welding is still used for metal-based artwork and in smaller home based shops, as well as situations where accessing electricity ( e . g ., via an extension cord or portable generator ) would present difficulties.
