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 ...
Women Who Weld is a nonprofit organization based in Detroit, Michigan. Women Who Weld teaches women how to weld and find employment in the welding industry through intensive and introductory welding training programs, including Week-Long Intensive Welding Training Classes and Single-Day Introductory Workshops.
This is a list of welding processes, separated into their respective categories. The associated N reference numbers (second column) are specified in ISO 4063 (in the European Union published as EN ISO 4063 ). [ 1 ]

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.
[7] Duty cycle is a welding equipment specification which defines the number of minutes, within a 10-minute period, during which a given arc welder can safely be used. For example, an 80 A welder with a 60% duty cycle must be "rested" for at least 4 minutes after 6 minutes of continuous welding. [8]
Electric resistance welding (ERW) is a welding process in which metal parts in contact are permanently joined by heating them with an electric current, melting the metal at the joint. [1] Electric resistance welding is widely used, for example, in manufacture of steel pipe and in assembly of bodies for automobiles. [ 2 ]
