Abstract
A welding method for subjecting a surface to be built-up of an elongated workpiece to a build-up welding process along a longitudinal direction of the workpiece, the welding method includes a step of forming a build-up layer on the surface to be built-up by supplying a filler metal to the surface to be built-up along the longitudinal direction and by applying a laser beam thereto to melt the filler metal. In the step of forming the build-up layer, information on a dimension of a molten pool formed by the filler metal and the workpiece molten by the laser beam is obtained, and an output of the laser beam is controlled based on the information.
