K Tig Welding Machine

Blessed with a team of dexterous professionals, our organization counted as leading Manufacturer & Exporter of K TIG Welding Machine in Anyang, Henan, China. Keyhole TIG technology is a new method which can realize "Keyhole" welding. It not only has the feature of ordinary TIG welding, but also the characteristics of deep penetration of plasma welding. The keyhole -TIG welding process achieves a relative balance between large arc currents (>300 A) and the surface tension of the molten metal in the pool, forming small holes (keyhole)to achieve deep penetration welding. During welding, the arc penetrates deep into the base metal, expelling the molten metal to the side walls of the pool and forming a keyhole. If the arc pressure, the steam reaction force formed by evaporation of the metal in the side wall of the hole, and the surface tension of the liquid metal are in dynamic equilibrium with the internal pressure of the liquid metal, the pinhole will be stable. As the arc moves, the metal in the pool melts behind the arc and solidifies into a weld. The process is very similar to the plasma (keyhole) welding method. The welding process is stable and delicate. The micro structure and mechanical properties of the weld are better than TIG welding.
