| Abstract: | The welding technology used for preheating flash butt welding was evaluated for workpieces with large welding section. The movement of the hydraulic proportion valve was controlled by a closed loop industral computer with the workpiece accelerated according to the predetermined flashing moving curve, so that the flashing process was violent but stabile. Both of the welding process control and the production management were integrated into the software control system. The system has many functions, such as transformation of the serial welding process, diagnosis and treatment of failures, parameter display and product number count, etc. The workpiece properties show that the welding system can be used to effectively flash butt welding large workpieces. |
