The weld detector consists of two parts, the launch and the receiver. The strip passes between the transmitter and the receiver. The transmitter emits a series of strip-shaped modulated infrared light. When the small hole near the welding bead is not in place, the beam is blocked by the steel plate, the strip receiver does not receive, and when the small hole near the weld is in place, the light is transmitted through the small hole to the receiver for receiving and outputting a switching signal.
