The invention discloses a stainless steel braid welding material and a manufacturing method thereof, and relates to the technical field of welding. The stainless steel braid welding material comprises a core wire and multiple strands of steel wire bundles. The whole core wire is in a round strip shape. The steel wire bundles wrap the outer surface of the core wire in the axis direction and are stranded and formed along the circumference of the core wire. Each strand of steel wire bundles is formed by stranding multiple thin wires. According to the stainless steel braid welding material and the manufacturing method, the stainless steel braid welding material which is adopted is high in melting speed, does not need large welding current, lowers the electrical energy consumption and is low in heat input amount, small in adverse effect on base metal thermal effect areas, small in welding deformation amount, good in stability during wire feeding, high in welding efficiency, good in quality and attractive in molding.
