Pipe Automatic Welding Machine

The pipe automatic welding offers good driving reliability. However, driven by frictional force, it is required to set essential balance weight to offset large bending moments caused by elbows for large diameter pipe, or providing a chain tensioner to improve the reliability of the driving.


The pipe automatic welding machine offers excellent welding capacity (250-350 inches/day, which is four times higher than manual welding).
The machine is easy to operate.
The pipe automatic welding machine offers excellent surface finishing.
It offers a welding qualification rate: (without re-working for the skilled operator).
