Document Type and Number:

WIPO Patent Application WO/2014/030325

Kind Code:

A1

Abstract:

The purpose of the present invention is to provide a welding system and welding method with which welding quality and welding speed in narrow groove welding can coexist easily. The welding system has a configuration that is provided with: a laser head for emitting laser light having a processing point beam diameter larger than the width of the groove of a pair of welding objects apposed with a narrow groove; a welding torch for arc-welding by applying voltage on a welding wire; a distance-adjusting mechanism for adjusting the distance between the laser head and the welding torch; and a moving unit for moving the laser head and welding torch, the distance between which has been adjusted, along the groove, causing melting inside the groove with the laser light emitted from the head, and arc-welding using the welding torch inside the melted groove to form the weld bead.
