OMM provide wide and flexible solutions by its new Single Shell Welding Machine with continuous welding, high welding quality, high welding penetration, conical round & polygonal poles welding, poles straightened, that make suitable this machine for poles production plant with a wide range of poles production typology.

OMM’s Single Shell Welding Machine can easily be operated and carried thanks to its user friendly interface. It's produced with latest production technologies able to guarantee the best results in term of poles welding.

Used for steel poles production, represent the solution for company that wants to produce poles (conical round & polygonal poles) with very wide range of poles typology with very high quality, reduced poles handling time and high production rate.

OMM’s Single Shell Welding Machine process independently conical round & polygonal pole starting from the top diameter or from the bottom diameter, up to 650 mm diameter.

This machine allows, starting from a bended trapezium, to weld the joint apply the correct force from the side and from the top in order to close the joint but without any shape deformation. To do that the machine check the value of the force applied and change it in according with the mechanical resistance (diameter and thickness).

OMM’s Single Shell Welding Machine simultaneously with the welding phase, straight the pole without using fire, guarantee a maximum bending on the total length not more that 2 mm (i.e. L = 16 m, Thickness = 5 mm)

All the process is managed by only one operator for parameters setting (poles length, top and bottom diameter, thickness) and supervisor.

Make a good pole, straight and good welded, it’s the first condition to don’t lose time and money on the repairing station.
