Cladding with AC/MIG

 

AC-MIG Cladding - Aufpanzern

The AC/MIG welding process from OTC DAIHEN, also known as the "cold welding process", is characterised by the precise synchronisation of the control of the welding current with the wire feed speed in order to control the molten pool. The Welbee 400 welding power source provides optimum control of the energy input, a high melting rate and sufficient burn-in control.

 

OTC DAIHEN demonstrates the new hardfacing process with AC/MIG cladding using the example of a roller for a conveyor belt system as it is known from the stone and earth industry: the component is given a finishing treatment by welding a corrosion-resistant, high-strength metal surface in order to later meet the abrasive production conditions in a rough environment.

The advantage of the AC/MIG cladding process when welding on the new layer is that only a small amount is mixed with the base metal. Strictly speaking, this is only enough to ensure a reliable connection between the base body and the weld deposit. This requires uniform mixing in the welding process, which is only possible using the AC/MIG process. According to the manufacturer, the mixing in the AC process is only 36% compared to the DC process.
