Product Overview
Solve your business pain points with innovative technical solutions
The PPGW series roller-press type automatic pipeline welding machine consists of a roller-press pipe welding positioner and a mobile cantilever welding machine. The roller-press pipe welding positioner drives the workpiece to rotate 360° and can also tilt the workpiece by ±45°, meeting the requirements for automatic welding of pipe-to-pipe, pipe-to-flange, bent pipes, T-pipes, and pipes of different diameters with center-of-gravity offset. The mobile cantilever welding machine can move along the track to the weld seam positions on both sides of the roller-press positioner for welding. One-time clamping enables automatic welding of weld seams at different positions on the pipe section.
