“EFD Induction is a specialist in induction welding and has up-to-date equipment that fits with our production process,” says General Manager Dennis Matthijssen at KS Roll Forming.
The new welding line can produce profiles up to 160 mm in height and 200 mm in width, with a thickness up to 4 mm, at a speed of 60 m/min. It has a pre-punch capacity 1,600 kN with 40 unique tools.
“Especially the combination of punching possibilities, together with the HF welding, makes this line unique and capable of producing a wide range of profiles,” Matthijssen explains.
In designing the new line, KS Roll Forming were able to draw on their considerable roll forming experience whilst relying on EHE Consumables for the welding process applications support.
Utilising two-piece flange mounted coils and return flow impeders, the first profiles were produced in a test run back in April. Since then, KS Roll Forming have introduced more complicated profiles into the mill and have worked closely with EHE Consumables in doing some fine tuning of OD bead removal for specific products.
