Research on Welding Performance of Silver Impregnated Graphite Contact Materials
AgC(30), AgC(40), AgC(50) and AgC(60) silver-graphite contact materials with different microstructure and properties were prepared by hot isostatic pressing process. The welding properties of silver-graphite contact materials with different carbon content were studied by means of welding force testing device. The results show that the welding force increases with the increase of contact current and carbon content. AgC(30) silver-graphite contact material has the best resistance of arc welding.
