High Frequency Automatic Pipe Welding Machine for Pipe Spool Fabrication Line

Pipeline welding machine is one of the most important links in the pipeline prefabrication production line, which determines whether the final pipeline is completely sealed and whether it meets the requirements. According to the different construction methods of each team, as well as different welding methods, we have the following welding machines, they have their own advantages, welcome to buy. 

1.      Pipe and Flange Fitting-Up / Tack Welding Machine (MIG/MAG/FCAW)

This type of chuck welding machine is suitable for straight pipe with flange and can be used for pipe alignment and pipe welding simultaneously.It can be welded straight pipe and flange directly,increasing the efficiency and quality of pipe-flange fit-up, needing fewer skills for fitting-up pipes and flanges and reducing work difficulty for the operators.The fast matching and automatic bonding between pipe and flange are realized, and the efficiency of butt welding between pipe and flange is improved.

2. Automatic Welding Machine for Piping Spool Prefabrication (FCAW/GMAW)/(TIG+MIG/FCAW)

For some heavy pipes that cannot be clamped, we adopt this cantilever welding machine. The pipes are placed on the material rack with rollers and welded by rotating the pipes.The pipe driven by frictional force, however, it is required to set essential balance weight to offset large bending moment caused by elbows for large diameter pipe, or providing a chain tensioner to improve the reliability of the driving.
