Abstract

　電極３７の先端面と金属板１１の端面との間にパルス状の放電を発生させて、電極３７を消耗させて、電極３７の先端面に金属板１１の端面の形状に即した窪み４１を形成し、電極３７を金属板１１の側面に対して直交する方向へ相対的に移動させつつ、電極３７の窪み４１の内側面と金属板１１の端面の側面１１ｂｌ（１１ｃｌ），１１ｂｒ（１１ｃｒ）との間にパルス状の放電を発生させて、金属板１１の端面の側面１１ｂｌ（１１ｃｌ），１１ｂｒ（１１ｃｒ）に、補助被膜４３，４５を形成し、電極３７の窪み４１の奥面と金属板１１の端面の先端面１１ｂｕ（１１ｃｕ）との間にパルス状の放電を発生させて、金属板１１の端面に肉盛層４７を形成する。
