1: STRUTURES OF Cold Pressure Welding Machines

Machine working principle:

This machine can release electrical power in capacitor with pulse arc form instantly onto tungsten and work pieces. The high temperature arc will make metal material work pieces and welding wire dissolve immediately and then welding together, and achieve welding effect. 

 2: ADVANTAGES OF Cold Pressure Welding Machines

short time and low calorific value.

This welding machine can finish melt between electrode and work pieces less than a second. Compared to normal welding machine (normal welding machine needs several seconds), the heat send to work pieces of this machine is very small. So, to work pieces, it is low calorific, low temperature increase except welding spot, no annealing, and no discoloration. As each welding pulse volume is less than 2mm³, so the stress is also small. Though the welding needs combine many dissolving pool, the welding spot stress direction is dispersive, so the deformation is very small after welding.
