Abstract
PURPOSE: To prevent lack of penetration, defects of bead appearance, etc. by controlling welding in such a way that the traveling of a welding carriage is started upon attainment of welding electric current at a reference welding current value.
CONSTITUTION: Reference welding current is set by a reference welding current setter 22a, and actual welding current is detected by a shunt 23 and is compared with reference welding current. When the actual welding current is larger than the reference current, the normally open contacts 24a of a relay 24 are closed, and the motor of a welding curriage runs at a high speed. When the actual welding current is small, the normally open contacts 24a of the relay 24 are opened to run the motor of the welding carriage at a low speed. Under automatic control in this way, vertical welding is accomplished by an electrogas welding method while a small diameter flux cored wire is oscillated at a high speed in the thickness direction within the groove of the work.
