Specially designed for automatic pipe-to-pipe butt joints. Compatible with iOrbital5000 and external wire feeders for precise orbital TIG welding.
System overview and applications
This welding head is specially designed for tube to tube TIG welding, suitable for carbon steel and stainless steel tube to tube butt joints. It's fit for fusion welding or wire feeding with an external TB1501 integrated wire feeder with AVC & OSC functions. It is compatible with iOrbital5000 programmable controllers to achieve accurate orbital TIG welding for tube/tube welding with high repeatability. It is mainly applied in chemical, food, medicine, engineering installation, boiler, nuclear and so on.
