[edit] Oxyfuel gas welding
| Name |
Characteristics |
Applications |
| Air acetylene welding |
Chemical welding process, not popular |
Limited |
| Oxyacetylene welding |
Combustion of acetylene with oxygen produces high-temperature flame, inexpensive equipment |
Maintenance, repair |
| Oxyhydrogen welding |
Combustion of hydrogen with oxygen produces flame |
Limited |
| Pressure gas welding |
Gas flames heat surfaces and pressure produces the weld |
Pipe, railroad rails (limited) |
[edit] Resistance welding
| Name |
Characteristics |
Applications |
| Flash welding |
|
|
| Pressure-controlled resistance welding |
|
|
| Projection welding |
|
|
| Resistance seam welding |
Two wheel-shaped electrodes roll along workpieces, applying pressure and current |
|
| Resistance spot welding |
Two pointed electrodes apply pressure and current to two or more thin workpieces |
Automobile industry |
| Upset welding |
Butt joint surfaces heated and brought together by force |
|
[edit] Solid-state welding
[edit] Other welding
| Name |
Characteristics |
Applications |
| Electron beam welding |
Deep penetration, fast, high equipment cost |
|
| Electroslag welding |
