What is TIP TIG? The TIP TIG welding process significantly improves weld quality. It sharply increases welding speeds by guid ... ing the preheated, oscillating filler wire directly into the weld pool to optimize and control the heat input and improve desertification. The preheated filler wire melts faster and substantially increases the deposition. The filler wire oscillation is transmitted to the weld pool and breaks the molten metal’s surface tension to keep the liquid flowing. This improves side fusion and further increases deposition rates. Higher deposition rates turn into faster welding speeds and less time for heat to dissipate into the base metal resulting in smaller heat-affected zones. read more
