Promotech MCM machines are true portable CNC cutting and welding machines already proven with several Customers in Wind Business, including multiple successful installations! It’s also the best solution for door frame welding to Tall Steel Wind Towers for Multi-Megawatt Turbines (welding door frames at plate thickness up to #65 mm and more on request). It is an unique option for unblocking bottleneck with door frame measurement, bevelling and welding.
Description
The application of a door frame to a wind tower, which requires cutting, beveling, assembling and welding processes, is a time consuming operation that deeply affects the manufacturing cycle.
Promotech’s MCM Machines – Portable CNC Oxy-Cutting & Beveling and SAW Welding accepts two technologies that apply door to tower:
■ Door frame welded directly on tower
■ Door frame welded in a rectangular plate, which is then welded in the tower section
■ Cutting & Beveling openings in Big-size Monopiles, and maximum plate thickness up to #150 mm
and It’s 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 finished welded seam of the door frame inside and outside tower section it’s confirmed by customers in Wind Business.
Top Features:
MCM scanning system: To obtain individual door frame shape for cutting/beveling and welding operations.
Simple and easy MCM control system: Any CNC programming is required nor costly operator’s training
One-man operation: One-man operation
Aperture automatic or semi-automatic MCM cutting and beveling: Minimized grinding / perfect door frame fitting
MCM SAW Welding (inside): Welding deposition rate from 8 to 11.6 kg/hour
MCM SAW welding (outside): Less than 1% of welding defect rate and no grinding by finished welded seam of the door frame inside and outside. It’s confirmed with Customers in Wind Business.
