PURPOSE: To feed filler wires safely and continuously by controlling the clearance of butting parts of a metallic strip at less than the diameter of a filler wire and feeding the filler wire and the controlled crearance as a guide.
CONSTITUTION: After a strip 1 is cramped by the upper and lower cramps, the strip is cut by the upper and lower shear and butted at less clearance than the diameter of a filler wire 9. After that, a lazer torch is run along the weld line and the beam is emitted to the butted part. The filler wire 9 is fed from the opposite direction of welding by following the weld line from a filler wire supply motor 10. In this case, a tip of the wire 9 from a guide tube 14 is fed to the weld line at the specified angle by taking the clearance of butted parts as a wire guide. Therefore, filler wires are welded continuously without wire bending and well penetrated wires and the high quality of weld can be obtained.
