CW400-600-800 Crankshaft Welding machine


The welding machine CW brings the bearing journals to their original dimensions, by welding new material following the submerged arc welding process; it is a process for which the electric arc is covered by granulated material called welding sand, than fuses the wire, and puts it on the shaft to be welded.

The welding sand is a composition of silicon, chromium, manganese, molybdenum, coal, etc., that completely covers the electric arc during welding operations. Furthermore, the welding sand protects the welding with a particular atmosphere and does not hurt the operatorr's eyes. A wire for welding crankshafts either for cars or for trucks is from 35 to 45 Rockwell C.

Our machine has a double wire selector for working with wires of different diameters, without changing them each time you need. Turn the proper switch to choose one or another. Moreover, the CW has the possibility of vertical movement, useful when crankweb welding is necessary.
