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 ]
For example, AWS B1.11 explains how to visually examine welds; AWS B2.1-1-004 explains welding carbon steel of thickness range of 18 through 10 gauge with semiautomatic metal gas arc welding; and AWS C2.20/C2.20M explains metalized zinc cathodic protection systems. Some codes also describe the standards used by AWS to certify welders ...
For example, so-called labor gangs, groups of men assigned to shoveling or other manual tasks, are not employed nearly as much as they used to be, especially in developed economies. Some jobs, despite being classifiable as semiskilled work, actually require quite a bit of talent and experience to be done well, for example, band saw operators or ...
Friction welding (FWR) is a solid-state welding and bonding process that generates heat through mechanical friction between workpieces in relative motion to one another. The process is used with the addition of a lateral force called "upset" to plastically displace and fuse the materials. [1]
While weldability can be generally defined for various materials, some welding processes work better for a given material than others. Even within a certain process the quality of the weld may vary greatly depending on parameters, such as the electrode material, shielding gases, welding speed, and cooling rate. [1]
The symbolic representation of a V weld of chamfered plates in a technical drawing. The symbols and conventions used in welding documentation are specified in national and international standards such as ISO 2553 Welded, brazed and soldered joints -- Symbolic representation on drawings and ISO 4063 Welding and allied processes -- Nomenclature of processes and reference numbers.

The Welding Institute (TWI Professional Group) is a direct descendant of the Institution of Welding Engineers Limited, which began when 20 men gathered on 26 January 1922 in the Holborn Restaurant in London and resolved to establish an association to bring together acetylene welders and those interested in electric arc welding. The date of ...
