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 ]
American Welding Society ATFs are listed on the official AWS website and advertised in the American Welding Society's Welding Journal magazine. The ATF program requires that a facility implements a quality assurance program that meets the requirements established in the AWS QC4-89, Standard for the Accreditation of Testing Facilities. [ 5 ]
Braze welding is the use of a bronze or brass filler rod coated with flux to join steel workpieces. The equipment needed for braze welding is basically identical to the equipment used in brazing. Since braze welding usually requires more heat than brazing, acetylene or methylacetylene-propadiene gas fuel is commonly used. The name comes from ...
