| Abstract: | The smooth control parameter of arc length for the all-position of tube girth welding is formed by the microcomputer technology and successive linear fitting arithmetic, for the purpose of realizing the self-adaptation control of arc length in all-position TIG tube welding machine, by real-time sampling arc voltage during pulse welding current period. And the control system has the advantages of high speed of dynamic response, high precise of adjustment, stable and reliable property of function. The experimental results show that the weld melt- width is even, and weld face shape is beautiful. |
