What is Welding?

Gas Welding FAQ

Gas welding is a type of welding that uses the combustion of gases or/and hydrocarbons to produce the weld by melting the weld metals. 

Gas welding is mainly used in sheet metal industries (Eg. Airplanes and Ships) and welding thin metals.

There are five types of gas welding: Oxy acetylene welding, Oxy-gasoline, MAPP, Propane/butane, and Oxy-Hydrogen welding.

Gas welding is also known as oxyacetylene welding because the commonly used gas is acetylene.

 Arc welding primarily makes use of electricity to generate heat to melt and join metals. Gas welding uses flammable gases to weld the metals.
