GTAW Improvements

There is a new welding process, recently developed in Europe, that is said to not only improve welds but also lower the skill required to make them.  It uses a “manual and automated GTAW wire feed control combined with a hot-wire power source” that improves the wire feed, weld pool, and weld deposition and decreases gas consumption.

Enhancing the GTAW process

Gas tungsten arc welding (GTAW or TIG), a popular process for high-quality manual welding, has its limitations and requires highly skilled operators. A process used in Europe addresses those limitations, enhances productivity and weld quality, and reduces the skill level required to GTAW.

For at least six decades, traditional gas tungsten arc welding (GTAW or TIG) has been considered the process of choice for attaining high-quality welds in any metal application. However, this process has certain drawbacks, such as the weld energy limitation influenced by the weld pool dynamics and typically slow manual wire feed rates. Manual GTAW requires highly skilled operators who possess the dexterity necessary to feed the wire. Manual GTAW techniques vary, and the weld-wire-to-arc and weld puddle placement are inconsistent.
