Abstract

PURPOSE: To correct welding conditions based on defect signals and prevent the continued production of weld defects by performing ultrasonic angle beam flaw detection from one or both sides of the weld zone leaving a fixed distance from an electrode wire.
CONSTITUTION: In submerged arc welding, the plural ultrasonic angle beam probes 1 on both sides of the weld line scan on groove faces 2 cooperatively with a welding torch at all times during welding, in the position apart by a distance l from a preceding welding wire 4 and on the line orghogonal to the weld line. If at this time lack of fusion 6 occurs on the groove faces, a defect signal 8 is outputted to operate a welding control unit which in turn moves the wire 4 to the signal generating side until the defect signal 8 annihilates. In addition, if lack of penetration 11 occurs on the under surface of root in the case of using one angle beam probe 1 on one side of the weld line, an output signal 9 is inputted to the welding control unit so that the welding current is increased or the welding speed is decreased, whereby normal welding is accomplished.
