A process called TIP TIG uses a constant-feed hot-wire that imparts additional energy to the weld. The wire also is superimposed by a secondary high-speed oscillation. The hot-wire’s current combines with the weld-pool agitation to disrupt the surface tension and change the weld dynamics.

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.
