摘要
研究TIG弧堆焊熔深控制方法,在分析TIG焊接特点和实际焊接过程的基础上,设计以熔深的偏差和偏差变化率为输入变量,焊接电流的变化量为输出变量的模糊控制器.并对控制器进行了仿真和实验验证.结果表明,控制器可以在5秒内达到稳定状态,熔深满足实际生产要求,设计的控制系统具有良好的控制效果.
The control method of penetration is studied in TIG welding. On the basis of analyzing the characteris-tics of TIG welding and actual welding process, the fuzzy controller is designed, its input variables are bias of penetration and change rate of bias, its output variables are the change of welding current, and the controller is simulated and verified by the experiment. The results show that the controller can reach a stable state in 5 sec-onds, that the penetration depth can meet the actual production requirements and that the designed control sys-tem has good control effect.
