Open type All-position Pipe-pipe Welding Machine

The equipment is specially designed for open-type & all-position TIG pipe-pipe welding. It adopts the wire-filling welding method, which is suitable for thickness 1.5-10mm pipe-pipe automatic welding. Applied for welding of carbon steel, stainless steel and other pipe-pipe joints. Optional for integrated wire feeder or external wire feeder with arc length swing function. It can be used with MK400 program-controlled welding power source to achieve all-position TIG pipe-pipe welding, with high repeatability of welding results and ideal welding effects. Mainly used in chemical, food, engineering installation, boiler, military and nuclear power and other industries.

Product Features

Automatic welding: The all-position automatic pipe-pipe welding equipment can be used for all kinds of thickness 1.5-10mm pipe joints, such as medium & thick wall of carbon steel and stainless steel.

Lightweight structure: The torch head is made of aluminum alloy and lighter structure. The calipers clamping method can be adjusted arbitrarily for different pipes.

Supporting welding powerCan be used with MK400 program-controlled welding power supply

Rotational stability: Adopted the design of gapless gear transmission with stable rotation, small rotation inertia, and little influence in high temperature working environment, no jamming on rotations.

Suitable for multi-layer welding: Arc swing design with arc length tracking system and swing wire feeding mechanism, suitable for multi-layer welding process requirements.

Long working hours: Torch head is recycled water cooling with continuous working times.

Wire-filling welding: It adopts the wire-filling welding method, widely applicable in scenarios.

All-in-one: Used integrated wire feeding device; external wire feeder is also optional.

Widely used: Applied on pipe-pipe and pipe-elbow multi-joint solutions
