SETTING METHOD FOR POWDER BRAZING MATERIAL

摘要

PURPOSE:To improve workability and to obtain a brazed product of good quality by forming a solid coating film of a thermally reactive adhesive agent on a part to be brazed, and reactivating said agent in the stage of a setting brazing filller metal. CONSTITUTION:A thermally activative adhesive agent which develops tackiness when heated such as an acrylic resin or vinyl acetate is coated on parts to be brazed. After these parts are once stored, the parts are heated to a required temp. to activate the coating film. A required amt. of powder brazing filler metal is put on the activated adhesive coating surface to set the brazing filler metal over the entire surface of the coating surface. Such parts are introduced into a furnace are heated. Thus workability is improved and the brazed products of good quality are obtained.
