Pulse Puddle Arc Welding (PPAW) creates a pulsating weld puddle while the weld metal is being deposited.
The idea of pulsating a liquid as it is being poured and solidifying is not new.This has been done for many years in cement, castings, dental, prostheses, and many other industries.

PPAW Equipment is engineered to be integrated into the welding station as well as in field operations and can be used as a complimentary process to high-frequency welding to produce an even higher quality of weld.
Why the Welding Industry needs PPAW?

90% Less Weld Distortion
Increase Welding Speed
400% Greater Ductility
