New pipe flange welding system for automated production lines

Fully automatic handling and welding processes for the efficient production of pipes with push-on flanges

The new generation of pipe flange welding systems – designed for nominal widths of 2 to 14” and lengths of 800 to 6,000 mm – offer plenty potential for rationalization. They have been conceived for fully automatic component infeed, welding and outfeed of pipes with push-on flanges.

Pipes are fed to the system from a pipe store. Robots then place the flanges in the right position in the clamping devices. The components are welded with 4 torches simultaneously. Up to 10 welding positions are pre-selectable. Internal scanning systems ensure that the torches are correctly positioned in relation to the component.

Welded pipe joints are fed out of the system by a discharge unit. This means that this MÜLLER OPLADEN solution is ideal for use on pipe production lines.

The welding proper of internal and external seams is performed by non-robot-controlled welding heads specially developed and built by MÜLLER OPLADEN. With these heads developed in-house, the system achieves much higher productivity when welding a variety of nominal widths than robotic welding stations, as set-up time is much shorter.
