Abstract
The invention concerns an automatic welding apparatus for plates. A regular reciprocatory scan is carried out by an optical sensor 18 of the joint 32 between two plates 28 and 30 to be welded: the sensor 18 moves transversely of the general direction of the joint to be welded which moves past under the welding torch 10 and under the sensor 18; the time interval between the instant when the joint is sensed and the instant when the sensor passes the axis of the torch is measured and the torch is moved transversely, by means of a motor 15, in response to the measurement of the time interval, in a direction corresponding to a reduction in this interval, so as to recenter the torch on the joint 32 to be welded. This arrangement avoids drift and possible disengagement from the joint which can occur in welding processes with continuous following of the joint.
