Tungsten Copper Electrode and Other Materials Comparison

Tungsten copper powder sintered material having high hardness, high density, high strength, wear resistance, adhesion, excellent electrical and thermal conductivity as well as sweating characteristics, making it ideally suited to withstand high stress resistance welding electrode matching, or as automatic submerged arc welding, carbon dioxide CO₂ gas shielded arc welding tip conductive or conductive plate. Tungsten copper flash welding electrode and chromium-copper comparison as follow:

 

From the table we can see that tungsten copper chromium copper compared to flash welding electrode welding electrode flash at the same working hours, higher welding efficiency, the amount of wear smaller, better weld quality, lower cracking rate life more long, the application is more convenient, and therefore wide range of applications. Vertical automatic welding, soldering conditions when the thickness of 22-28mm, wire directly Φ2.4mm, conductive nozzle aperture when 2.8mm, tungsten, copper and chromium copper conductor conductive nozzle tip wear after welding is very different.

Tungsten copper conductive tip after welding 20m, the aperture remains the prototype, you can still continue to work, in contrast, chromium copper conductive soldering tip less than 2m, its conductivity unilateral eccentric bore wear, maximum diameter enlargement ratio of tungsten copper conductor increases 0.6mm, has been unable to proceed with the welding work. Therefore, resistance welding electrodes and welding conductor tungsten copper powder sintered material having a high hardness, high density, high strength, wear resistance, adhesion, excellent electrical and thermal conductivity and a series of advantages, which has a broad prospect.
