By 1916 the oxyacetylene process was well developed, and the welding techniques employed then are still used. The arc is between a continuously fed filler metal (consumable) electrode and the workpiece. Filler materials are generally added into this molten material, and the two ends are joined together and allowed to cool, forming one solid piece. The tungsten electrode delivers the current to the welding arc. In this process, mostly oxy-acetylene gas is used as fuel gas. In this welding, a thin wire acts as the electrode which is fed from a spool mounted on a gun through a flexible tube and it comes out of the nozzle on the welding gun or torch. The major cause of undercuts in welding is when the operator (welder) uses a high welding current or welds with fast travel speed. What is the definition of gas welding?
