Intro:Weld detector consists of transmitter and receiver
two parts, sheet metal from the transmitters and receivers,
passing through the middle transmitters emit a beam of
banded by the modulation infrared, near weld holes not by
then, the beams are steel plate cover, can't reach the
receiver, the weld seam when they arrive, the light through the
holes near weld received by receiver, and through the
subsequent processing circuit, a switch quantity output signal
