Gas welding is a process that melts and joins metals by heating them with a flame caused by the reaction of fuel gas and oxygen. This process can be used for many different industries, but it is most commonly used in metalworking. The most common type of gas welding is Oxyacetylene welding, due to its high flame temperature.
The flux may be used to deoxidize and cleanse the weld metal. This is typically done with a gas welding machine, which uses valves that control the flow of oxygen and fuel gases into an open flame or electric arc.
The process takes place in three steps: heating up the weld area; melting the metals together; cooling down the joint for solidification.
