Advanced P+T Double Torches Welding Process
Principle
To use plasma keyhole effect to get reliable and stable backside shaping, and TIG welding with wire feeding 200-300mm after plasma welding to get better front seam performance.
Advantages
More effective and better welding performance compared to single plasma torch weldingHigh and reliable welding quality30%-50% more efficient than TlG/PAW weldingSuitable for welding stainless steel,titanium alloy,zirconium alloy or other rare metal materials.
Principle
The arc between electrode and workpiece is compressed by special torch structure and forms stable compressed plasma arc to melt the workpiece to get deep penetration.There are three types of arc,i.e.transferred arc,non-transferred arc,combined arc is commonly used.
