Abstract

An arc welding head is automatically guided in line with the joint by a photocell and a servo control with shapers of a negative or positive signal to correspond to the photocell being to the right or left of the joint. Both shapers feed an adder and an integrator. The electrode in the welding head is controlled directionally by a correcting element, fed from the control unit via a coincidence circuit at the output of the integrator.
