PROBLEM TO BE SOLVED: To provide a method for welding a coating material which forms gauze using the coating material for corrosion proof. SOLUTION: The coating material 3 is produced from a metal core material 1 and a synthetic resin film 2 which coats the core material and is incorporated with a granular or fibrous electro-conductive material 4 of a metal such as stainless steel. A welding current is applied to the crossing overlap part or the joining contact part of the coating material while being pressurized. By the melting of the synthetic resin film associated with the heat generation of the electro-conductive material, simultaneously with the welding between the resin films, the welding 6 between the core materials is carried out.
