IPC: B23K9/127
Filed: 1985-10-08
Abstract: PURPOSE:To make the weld line profiling at real time by finding the oscillating conditions based on the oscillation at previous time and by changing to the optimum oscillating speed and arc length responding speed when reaching to the position found by the oscillating electrode. CONSTITUTION:In the TIG welding performing arc voltage detecting type arc length control, the oscillation width and oscillation center are found based on the data of the half oscillation cycle at the previous time and the necessary electrode position for the all oscillation width is found as well. With reaching to the position where the electrode under oscillation finds at least one part of the speed of the oscillation speed and arc length control responding speed is changed to the most optimum speed for detecting a groove wall. In case of there being an abrupt change in the arc voltage, the motor for oscillation is driven with its reversing by deciding that the electrode reaches to the groove wall. The automatic welding can thus be performed by detecting the weld line at real time.
