TIP TIG is a subset of gas tungsten arc welding (GTAW), using a mechanism called filler wire agitation which enhances molten weld puddle dynamics and this agitation has been found to enhance the weld puddle fluidity and release evolving gases, reducing the chances of inclusions and porosity, and also separate impurities.
Welding systems that employ the TIP TIG method are in fact GTAW systems, simply wire fed, that additionally induce a vibratory effect on the wire and apply hot wire current on the filler metal before it even enters the weld pool. The vibration comes from a linear forward and backward motion applied mechanically using a custom wire feeder system. A secondary power, on the other hand, creates the hot wire current.
