types of welding joints and their applications

The welding process to be used has a major effect on the selection of the joint design. Weld metal is also shielded by the slag formation from flux melting. There are several types of joints that are used to connect structural parts. They are most commonly used to joint two pieces with differing thicknesses together. A power supply is used to create an electric arc is between an electrode (which can be either consumable or non-consumable) and the base metal to melt the metals at the point of contact. G.I pipe is used to supply gas, water, or any other liquid within the building. An oxygen gas canister and a fuel gas canister is connected to the welding torch. salary data.
