Investigation on Microstructure and Property of Non-Electric Welding Joint

Abstract:

Non-electric welding is a novel efficient technique for emergency maintenance, which utilizes the heat released by combustion reaction to join metals without needing any power supply or gas sources. Welding experiments were performed with 45 steel as the weld object, and results showed that the weld metal jointed the weld object in a metallurgic connection with the tensile strength above 280 MPa, which proved non-electric welding a fusion welding technique. Non-electric welding technology has advantages of simple operation and good mechanical performance, therefore possesses a promising application prospect.
