Down to the smallest detail: The different types of the LBS model line coil joining machines

Taking a closer look at the details of the type LBS coil joining machines is worth your while. Here you can see the technical details, the typical functional ranges and more detailed information on the technology behind the arc welding machines. You will learn why IDEAL utilises modular mechanical engineering in order to fulfil your requirements and expectations.

The technical data

Coil thicknesses 0,2 to 10 mm
Coil strength [N/mm2] 500 – 1.500

Arc welding machines made by IDEAL are used by leading manufacturers for the welding of coils of various dimensions and materials

The electric arc forms the basis of arc welding. It is created by an electric discharge between the welding electrode and the workpiece. The electric arc welds the coils of equal or different materials. Different welding current sources are available for each coil welding machine. The welding current source to be selected for the individual case depends on the material quality, coil thickness and coil surface. Alternatively, we offer flash butt welding machines with separate coil end shears, insertion stops, centring devices and plane deburring for the welding of steel coil up to a width of max. 800 mm.
