PROBLEM TO BE SOLVED: To provide an application method of a brazing material capable of applying uniformly and effectively a molten brazing material onto a long-sized cylindrical workpiece, and suppressing decline of mechanical strength of the workpiece.SOLUTION: There is provided a method for applying a brazing material onto a cylindrical workpiece by using an ultrasonic welder. In the application method of the brazing material, application is carried out so that an acute angle θ formed between an inner peripheral surface of the cylindrical workpiece and a vibration direction of an ultrasonic wave irradiated from the ultrasonic welder satisfies inequality θ≤40°.SELECTED DRAWING: Figure 1 【課題】長尺の円筒形被加工物に対して、溶融ロウ材を均一かつ効果的に塗布することを可能とすると共に、被加工物の機械的強度の低下を抑制し得るロウ材の塗布方法の提供。【解決手段】円筒形の被加工物に超音波ウェルダーを用いてロウ材を塗布する方法において、円筒形の被加工物の内周面と超音波ウェルダーから照射される超音波の振動方向となす鋭角θがθ≦４０°となるようにして塗布するロウ材の塗布方法。【選択図】図１
