The TIP TIG arc welding process

The TIP TIG Arc Welding Process, a New Type of WeldingThe TIP TIG arc welding process is a unique hot wire TIG welding process for automated welding, bore cladding, orbital welding, and aluminum welding that uses our patented wire feed technology. Our system’s benefits will provide the highest quality, highest deposition rates with the lowest possible heat input. TIP TIG is consistently delivering the most excellent metallurgical results on any alloys. It has also proven to provide the lowest possible hexavalent chrome weld fume emissions, measured as undetectable.

Unlike nearly all other hot wire TIG welding processes, it can be operated manually in all positions and with our patented automation systems. A widely recognized benefit we deliver is the reduction in labor costs associated with costly rework and training.

Simply put, it’s just simple to use, to teach, and to learn!

The TIP TIG welding machines are wire fed TIG systems that create a vibratory force on the welding wire and apply hot wire current to the filler metal before entering the weld puddle. The vibratory effect is created by a sinusoidal mechanical agitation created by the custom wire feeder system. The hot wire current is created by a secondary power source within the TIP TIG welding machine.

Take some time to explore the benefits of TIP TIG.

How it works

The mechanical action of the forward and backward motion of the filler wire creates an oscillation transferred into the weld. This agitates the molten weld pool, which then disrupts the surface tension.

The combination of these processes produces the following benefits to the weld:

  • Increased fluidity of weld pool
  • Greater tolerance to joint fit-up – Significantly reduced joint sensitivity
  • Greater ability to accept more wire into the weld pool – Higher deposition
  • Increased travel speed 4-6 times faster – Reduced cycle time and heat input
  • Agitated weld pool – Cleaner welds
  • Reduced heat input – Reduced weld stress

Why we’re different

TIP TIG is the only semi-automatic weld process capable of consistently producing optimum, all position code quality welds on carbon steels or any alloy applications without concern for weld rework and without fear of the effects of weld heat on the alloys welded.

TIP TIG is the only process capable of delivering the highest possible weld energy (optimum fusion – minimum porosity) with the significant benefit of also providing the lowest possible weld heat. These two benefits are necessary to attain consistently optimum code quality welds and resolve most alloy weld issues with regular TIG and pulsed MIG.

With TIP TIG, the continuously fed weld wire is superimposed by a secondary, high-speed oscillation generated by the patent-pending four rolls, a mechanized drive plate. The drive plate’s mechanical action generates a vibration that passes through the welding wire into the weld. The vibration agitates the weld pool. A further influence on the TIP TIG weld is the hot wire current, which preheats the welding wire, improving the TIG weld’s wire receptivity. The agitation of the TIP TIG weld and the added weld energy creates unique TIG weld dynamics, which slow down the weld solidification. Enabling longer TIG weld fluidity allows more TIP TIG weld wire to be fed into the weld pool. The increase in TIP TIG weld wire enables more weld current, further enlarging the TIG arc plasma and further increasing the weld energy. This also reduces arc length sensitivity and improves arc stability.
