Intelligent Control System of Welding Torch´s Attitude for Pipeline Welding Robot

Aiming at the control problem of the welding torch´ attitude in the case of whole-position welding, an intelligent control system of welding torch´s attitude for pipeline welding robot is presented in this paper. The ADXRS300 micro-mechanical gyro is used as the welding torch´s position sensor in this system. When the welding torch´s position is obtained, an appropriate pitch angle can be obtained through the experiential inference of the expert system. ARM is used as the controller to drive the welding torch pitch angle step motor in order to real -time adjust the pitch angle of the welding torch. The experiment result shows that the intelligent control system of welding torch´s attitude using expert system is feasible and it enhances the welding quality. This system has wide application prospect.
