  • Cutting & Beveling openings in Big-size Monopiles, and maximum plate thickness up to #150 mm.
  • It’s a one-man operation.
In all cases MCM machines produce perfect joints, door frame fit up and MCM SAW welds in “full penetration” class acceptability level B according to ISO 5817. Less than 1% of welding defect rate and no grinding by the finished welded seam of the door frame inside and outside tower section it’s confirmed by customers in Wind Business.
