Abstract
PURPOSE: To perform the uniform penetration of welding parts and an optimum speed increase of welding machine and cover plates, by controlling a position of torch with a detecting signal corresponding to the light or heat of each detecting element, which is placed oppositely at the specified position of both sides of each cover plate of copper as a detecting element or groups of element more than one.
CONSTITUTION: Copper cover plates 2a, 2b at both sides of base material 1, 1', slide upwards along a bevelling 3, accommodating to the progress of welding by a wire 4, and form a slag bath 5 and molten pool 6 between them. In the cover plates 2a, 2b, for example, thermocouple 7 of plural number are burried at the specified places before and behind, left and right along the progressing direction of welding and opposedly clamp the base material with more than one place. Adjust-controlling of the opposite position of torch 8 to the base material is performed by a motor 12 driven by an output of differential amplifier to make a driving control circuit become zero, wherein the difference will be caused in the quantity of heat received by left and right elements FL, FR in a case of uneven penetration at the left and right sides of the base material 1, 1. Controls on a welding voltage, a position of torch along the direction of base material's thickness, speed increase of welding instruments and copper cover plates, and flux quantity for adding are performed in the same way.
