| American Welding Society (AWS) | in charge of welder certification requirements, welding codes, and industry acceptance of good welds |
| Automated operation | welding operations are performed repeatedly by a robot or another machine that is programmed to perform a variety of processes |
| Automatic operation | welding operations are performed repeatedly by a machine that has been programmed to do an entire operation without the interaction of the operator |
| Certification | passing of an industry standard test to allow a welder to only make welds specified in the test they passed |
| Coalescence | the growing together or growth into one body of the materials being welded |
| Flux cored arc welding (FCAW) | an arc welding process that uses an arc between a continuous filler metal electrode and the weld pool. The process is used with shielding gas from a flux contained within the tubular electrode, with or without additional shielding from an externally supplied gas, and without the application of pressure. |
| Forge welding | method of joining pieces of iron together also known as hammer welding |
| Fusion welding | any welding process or method that uses fusion to complete the weld |
| Gas metal arc welding (GMAW) | an arc welding process that uses an arc between a continuous filler metal electrode and the weld pool. The process is used with shielding from an externally supplied gas and without the application of pressure. |
| Gas tungsten arc welding (GTAW) | an arc welding process that uses an arc between a tungsten electrode (nonconsumable) and the weld pool. The process is used with shielding from an externally supplied gas and without the application of pressure |
| Machine operation | welding operations are performed automatically under the observation and correction of the operator |
| Manual operation oxyfuel brazing (TB) | torch brazing, a brazing process that uses het from a fuel-gas flame |
| Oxyfuel (OF) gas | a gas mixture between pressurized oxygen and any pressurized fuel gas such as acetylene, propylene, propane, etc., to create a high temp preheat or cutting flame |
| Oxyfuel gas cutting (OFC) | a group of oxygen cutting processes that uses heat from an oxyfuel gas flame |
| Oxyfuel gas welding (OFW) | a group of welding processes that produces coalescence of workpieces by heating them with an oxyfuel gas flame. The processes are used with or without the application of pressure and with or without filler material. |
| Qualification | the ability of a welder to demonstrate his or her skills to produce welds meeting prescribed standards |
| Resistance welding | group of welding processes that produces coalescence of the faying surfaces with the heat obtained from resistance of the workpieces to the flow of the welding current in a circuit of which the work pieces are a part and by the application of pressure |
| Semiautomatic operation | during the welding process, the filler metal is added automatically, and all other manipulation is performed by the operator |
| Shielded metal arc welding (SMAW) | an arc welding process with an arc between a covered electrode and the weld pool. The process is used with shielding from the decomposition of the electrode covering, without the application of pressure, and with filler metal from the electrode |
| Weld | a localized coalescence of metals or nonmetals produced either by heating the materials to suitable temperatures, with or without the application of pressure, or by the application of pressure alone and with or without the use of the filler material |
| Welding | a joining process that produces coalescence of materials by heating them to the welding temperature, with or without the application of pressure or by the application of pressure alone, and with or without the use of filler metal |
