Title:
WELDING SYSTEM AND WELDING METHOD
Document Type and Number:
WIPO Patent Application WO/2018/230419
Kind Code:
A1
Abstract:
Provided are a welding system and a welding method, which are able to easily stabilize the welding quality. This welding system is provided with: a welding device (10) which performs buildup welding by fusion bonding a welding material to a surface (4) of a work (2); a preheating device (30) which preheats the work (2) and subsequently retains the heat; a control device (18) which operates the welding device (10) and the preheating device (30) so that the buildup welding is started after the preheating of the work (2); and a first sensor (40) that measures a first temperature of a welding material (6), at which the welding material (6) is melted at the surface (4) of the work (2) by means of the welding device (10). The control device (18) controls the output of the preheating device (30) on the basis of the first temperature during the time when the buildup welding is performed by the welding device (10) so that the first temperature is within a predetermined first range.
