Study of Explosive Welding Technology of Railway Connector

Railway signal transmission is the key to insure train run safely.The railway connector for signal transmission is important equipment to guarantee railway signal transmission and reduce electric current imbalance.From the point of view of engineering practice,the explosive welding technology of railway connector was studied theoretically and experimentally,the appearance,tensile strength, micro configuration of welding junction and welding area after explosive welding were detected.Experimental and detective results show that the junction quality to concent railway with connector by means of explosive welding is reliable,which lays the foundation for the technology's engineering practice.
