Zusammenfassung: | To provide a hybrid welding method and a hybrid welding apparatus that can perform welding without dropping a weld metal even in a case of butt-welding in which a gap is present between base materials.A hybrid welding apparatus 1 according to the present invention is a hybrid welding apparatus that butt-welds a first joint J1 and a second joint J2 using laser welding and arc welding, and includes a laser welding device 2 that includes a laser head 21 that irradiates laser light L to a welded portion and an arc welding device 3 that includes a welding torch 31 that supplies a filler metal W to the welded portion. It is configured such that the laser head 21 is capable of performing horizontal welding and disposed on an upstream side in a welding direction, the welding torch 31 is capable of performing horizontal welding and disposed on a downstream side in the welding direction, and horizontal welding is performed with the first joint J1 and the second joint J2 disposed vertically so as to obtain a substantially horizontal weld line. |
