Abstract

PURPOSE: To hold back bead shapes to correct shapes by burying photoelectric photo detectors in the specified 6 positions of the light transmitable backing material for one-side automatic welding and controlling welding conditions by the electric signals of these photo detectors.
CONSTITUTION: Six photoelectric photo detectors 11 (F'R, F'L, M'R, M'L, B'R, B'L) such as of photo diodes, etc. are buried spacially at the specified distances in the specified positions empirically determined from the point right under a torch 5 respectively in the backing strip 8 in contact with the light transmittable backing material 10 (glass fiber) of the base metal 1 to be welded. The photo detectors 11 receive the transmitting light and emit respectively corresponding signals FR, FL, MR, ML, BR, BL. These addition signals cause the control mechanism not illustrated to move the backing strip 8 to the specified position right under the torch 5. At the same time, the addition signal BL+BR is compared with the preset back bead correct shape signal and welding conditions such as welding current, voltage, torch moving speed and other are controlled so that the back bead shape is maintained at the correct shape.
