| SMAW - Shielded Metal Arc Welding or Stick Electrode |
SMAW is an electric arc welding process in which heat for welding is generated by an electric arc between a covered metal electrode and the base metal. The electrode coating provides shielding. The welding equipment for this process is
|
| GTAW - Gas Tungsten Arc Welding or Tig Welding |
Tig Welding is easily performed on a variety of metals. It is an electric welding process in which heat for welding is generated by an electric arc between the end of a non-consumable tungsten electrode and the base metal. |
| FCAW - Flux Cored Arc Welding |
Flux is contained within the electrode. It provides shielding, deoxidization and arc stabilization. |
| GMAW - Gas Metal Arc Welding or Mig Welding |
Gas metal arc welding is quick and easy on thin-gauge metal as well as heavy plate.The two most common types of GMAW are:
- Short Circuit Transfer - The arc is broken or short-circuited with each drop of metal and restarted. It is used on smaller, thinner gauges and produces a shallow weld.
- Spray Transfer - Metal is transferred across the arc creating a continuous spray of fine droplets of metal. These droplets are projected down to the base metal.
