纳米改性涂层及焊接工艺参数对无镀铜实心焊丝导电嘴磨损影响的研究进展
Progress in Effect of Nano-modified Coatings and Welding Process Parameters on Wear of Contact Tube for Non-copper Coated Solid Wires
摘要
Abstract
Environment-friendly non-copper coated solid wire is the main developing trend for gas shielded solid wires ,whereas wear of contact tube limits their wide application .The effect of nano-modified coatings and welding process parameters on wear of contact tube for non-copper coated solid wires was reviewed .It was found that the wear of contact tube can be reduced due to the formation of tribo-films on the rubbing surfaces of welding wires against contact tube;it is feasible to decrease con-tact tube wear when non-copper coated solid wires are coated with nano-modified lubricants ,thereby displaying excellent lubricating and thermal or electrical conduction characteristics .The wear of con-tact tube increases with the increase of welding current .The wear of contact tube is worse in direct-current electrode positive (DCEP) than in direct-current electrode negative (DCEN) .Arc ablation and electrical erosion are the dominant wear mechanisms of contact tube .关键词
