There are 3 major CSA Standards to which welders may be qualified: CSA W47.1 [4] for steels (including stainless steels), CSA W47.2 [5] for aluminum, and CSA W186 [6] for reinforcing bars. Under these CSA standards, welder qualification testing is carried out every 2 years by the Canadian Welding Bureau to ensure ongoing competence.
The Canadian Welding Bureau, through CSA Standards W47.1, [3] W47.2 [4] and W186, [5] specifies both a WPS and a Welding Procedure Data Sheet (WPDS) to provide direction to the welding supervisor, welders and welding operators. The WPS provides general information on the welding process and material grouping being welded, while the WPDS ...
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.
The main advantage of extrusion welding is that it can achieve very high deposition rates of filler material into a joint, thus cutting down on cycle time. As compared to hot gas welding, which is a polymer welding process that could have many of the same applications, the time to completion for a weld is as much as 5-6x faster. [1]
ITW brought to Miller the resource base and global perspective needed to further strengthen the company's position as a world leader in the welding industry. [5] In 2002, it became the first U.S. welding equipment manufacturer to comply with the new ISO 9001:2000 standard. [6]

The electrical energy for the percussion welding can be supplied by a transformer, as alternating current (or rectified), or by the discharge of capacitors.Because of the short duration of the arc and of the fact that all of the weld energy comes from this arc, the electrical resistance of the parts to be welded does not affect the amount of heat generated at the weld and substances of ...
