To perform build-up welding in a correct shape even when the extension directions of each part to be added by the build-up welding are different for each part, in a build-up welding method for a member where pulselike discharge is generated between a member provided with electrical conductivity and an electrode for deposition, the electrode material for the electrode for deposition is deposited on each part of the tip of the member by the discharge energy and the end part of the member is subjected to build-up welding, .
In the build-up welding method for a member where the electrode material of an electrode E1 for deposition is deposited on each part of the tip 3 of a member 1, and tip 3 of the member is subjected to build-up welding, when the extension directions of each part to be added by the build-up welding are different for each part, the electrode E1 for deposition is moved relatively to the member in the extension direction of one part among the parts so as to perform build-up welding, the electrode E1 for deposition is moved to the part different from the above part and is installed therein, and the electrode for deposition is moved to the elongating direction of the above different part so as to perform build-up welding.
