The System Design of Automatic Rail Gas Press Welding

Abstract:

Rail gas press welding is a sophisticated process which involves physics, chemistry, heat transfer, material metallurgy and hydromechanics and other subjects concerned. The welding phenomenon includes heat transfer process during the welding, melting and coagulation of the metal, cooling change, welding stress, distortion and so on. In order to gain a fine welding structure, one must design the craft plan properly and scientifically. This paper introduces an automatic rail gas press welding solution, to which the core of DSP is applied to obtain the best welding effect.
