Inventor: WADA TAKAO
IPC: B23K9/028
Filed: 1981-02-25
Abstract: PURPOSE:To maintain the shape of beads constant and to improve the reliability of joints in welding waveform parts from flat parts, by detecting the speed of a welding torch on a Z-axis and moving the welding torch on an X-axis at the speed of the  mathematical expressionIfrom said detected speed and the preset welding speed. CONSTITUTION:In accordance with the rotating speed of a motor 5, the speed of a  welding torch 3 in a Z-axis direction is detected with a detector 37. At this time, it is  necessary to change the speed Vx in an X-axis direction by the equationIaccording to  the change in the speed Vz in the Z-axis direction in order to maintain the welding speed Vw constant. Thereupon, the speed Vz in the Z-axis direction is detected and is  squared with a circuit 38, the output of which is applied to a subtractor 39. On the  other hand, the signal from a circuit 40 setting the speed Vw is squared with a circuit  41, and is applied to the subtractor 39. Next, a circuit 42 operates the equationI, and  applies the result thereof to a subtractor 43, then a motor 4 moves the torch 3 in the X-axis direction. Thence, the speed Vx in the X-axis direction is detected with a detector 44, and is inputted to the subtractor 43. The motor 4 is so controlled that the speed Vx in the X-axis direction calculated with the circuit 42 coincides with the  actual speed detected with the detector 44.

A video signal from an image pickup part 2, therefore, has only its low-frequency component made into a low-contrast signal by a low-frequency differentiator 12 first and then the peak value of the low-contrast signal is obtained by a following peak holding circuit 13. Then only its high-frequency component becomes the high-contrast signal by a high-frequency differentiator 22 and the peak value of the high-contrast signal is obtained by a following peak holding circuit 23. Consequently, even when the defocusing of the initial stage is terrible, the focus adjusting operation can securely be started and the focus adjustment time is also shortened.
