A new method of resistance butt welding without the end preparation of workpieces is developed. The influence of welding current and initial platen velocity on the process of the weld formation are discussed and the mechanical and metallurgical properties of the welded joints are experimentally investigated. In conclusion, the welded joints with good quality can be easily obtained under certain welding conditions by new resistance butt welding process and in this welding process, the abutting surface of the workpieces is fused by intensitve Joule's heating due to high current density and high contact resistance constructed by the flashing of 1-2 cycles, and the oxide at the interface of the welded joint can easily disperse into the molten metal layer in the weld.
