Abstract
PURPOSE: To make it possible to automatically control the welding current and stably perform the operation, by substituting the width of the welding zone by the pulse width of an image sensor output signal.
CONSTITUTION: The width of the welding zone of a metallic conduit 1 which has been shaped like a pipe by a metallic tape forms an image on the end 6 of the image scope 4 through the mirror 2, the lens 3 and the image scope 4. This formed image 7 is made to form an image on the photodetecting surface of the linear array image sensor 9 through the image formation lens 8. The envelope pulse width of an image sensor output signal 10 corresponding to this image is proportional to the width of the welding zone. This output signal 10 is shaped through the comparator 11, and a signal 12 is obtained. The pulse width is obtained by counting the number of clock pulses which are contained in this signal 12, and both the pulse widths are compared by the pulse width comparator 14 which provides the reference pulse width set point 13. The signal which has been compared is processed by the signal processing circuit 15, the current control signal is supplied to the welder, and a proper current is selected.
