Eastern Welding Automations history with Hot Wire Tig has been extensive. Our strong relationships with nuclear and navel institutions in development of this process and its equipment give EWA the ability to train and develop this niche process for your part applications.

Hot wire TIG produces consistent quality welds at high production rates. The process pre heats the wire prior to transfer in an automated TIG process, virtually eliminating porosity by driving off most of the volatile contamination from the surface of the wire. By preheating the wire it also allows for faster deposition rates up to 14 lbs. per hour. The process is spatter free and maximizes control of dilution, bead width and surface profile.

The system is integrated to a fully mechanized system with pc based control and manipulation of circumferential or linear motion. Development of the process head is usually part specific.

Industry applications
Nuclear
Pipe/tank fabrication to code spec or pressure vessel Shipbuilding
Power generation
Corrosion resistant and sour gas / cracking tower applications

If your dealing with issues from porosity, contamination, lack of speed or quality of welds, due to difficult materials or inconsistency in consumables than EWA could have the answer.
