Automatic Pipe Spool Welding Machine


The M3 welding system provides users with unmatched productivity due to its integrated pipe welding cell. This fully automatic pipe spool welding machine is highly specialized for industrial spool prefabrication. With full penetration welds and no interpass cooling, the innovative package offers root-to-cap welds with 80-90% arc-on times, providing a revolutionary tool to any pipe fabrication company.

As an automatic pipe spool welding machine, the M3K is the keyhole version specially developed for single-pass industrial pipe or small pressure vessel manufacturing. The nexus of this state-of-the-art technology is the welding machine’s vision-allocated penetration system. Acting comparatively to a traditional welder’s keen eye and hands, the automated system observes the original weld pool image via an integrated video camera installed into the welding arm.

Attributable to the camera-based and robotized nature of the M3K automatic pipe spool welding machine, minimal welding experience is necessary for successful results. Other technical specs and capacities include:
