TIG Welding
Gas Tungsten Arc Welding (GTAW) is frequently referred to as TIG welding. TIG welding is a commonly used high quality welding process. TIG welding has become a popular choice of welding processes when high quality, precision welding is required.
In TIG welding an arc is formed between a nonconsumable tungsten electrode and the metal being welded. Gas is fed through the torch to shield the electrode and molten weld pool. If filler wire is used, it is added to the weld pool separately.
TIG Welding Benefits
Welds can be made with or without filler metal
Precise control of welding variables (heat)
Free of spatter
Low distortion
MIG Welding
Gas Metal Arc Welding (GMAW) is frequently referred to as MIG welding. MIG welding is a commonly used high deposition rate welding process. Wire is continuously fed from a spool. MIG welding is therefore referred to as a semiautomatic welding process.
MIG Welding Benefits
All position capability
Higher deposition rates than SMAW
Less operator skill required
Long welds can be made without starts and stops
Minimal post weld cleaning is required
Stick Welding
Shielded Metal Arc Welding (SMAW) is frequently referred to as stick or covered electrode welding. Stick welding is among the most widely used welding processes.
The flux covering the electrode melts during welding. This forms the gas and slag to shield the arc and molten weld pool. The slag must be chipped off the weld bead after welding. The flux also provides a method of adding scavengers, deoxidizers, and alloying elements to the weld metal.
Stick Welding Benefits
Equipment used is simple, inexpensive, and portable
Electrode provides and regulates its own flux
Lower sensitivity to wind and drafts than gas shielded welding processes
All position capability
