Metal fabrication is the creation of metal structures by cutting, bending and assembling processes. It is a value-added [ 1 ] process involving the creation of machines, parts, and structures from various raw materials.
Electroslag welding (ESW) is a highly productive, single pass welding process for thick (greater than 25 mm up to about 300 mm) materials in a vertical or close to vertical position. (ESW) is similar to electrogas welding, but the main difference is the arc starts in a different location. An electric arc is initially struck by wire that is fed ...
Since the move to advertising, the Welding Journal has been published continually and continues to be an resource for issues and advancements concerning all types of materials joining, metal fabrication, and construction. It is offered as a benefit to members of the Society, and includes information of the latest products, trends, technology ...
A welder is a person or equipment that fuses materials together.The term welder refers to the operator, the machine is referred to as the welding power supply.The materials to be joined can be metals (such as steel, aluminum, brass, stainless steel etc.) or varieties of plastic or polymer.
Gas metal arc welding is a semi-automatic or automatic arc welding process in which a continuous and consumable wire electrode and a shielding gas are fed through a welding gun. A constant voltage , direct current power source is most commonly used with GMAW, but constant current systems, as well as alternating current , can be used.
