Analysis of Key Technical Points of Tubes Flame Brazing Process
In this paper,the flame brazing process of thin-wall 321 stainless steel tube with silver base brazing filler metal was studied,and the technical points and key parameters of brazing tube with AMS 4772 silver base brazing filler metal were described.The results show that the joint with good appearance,sealing performance and brazing spread rate can be obtained by using the flame brazing process,and the brazing quality can meet the relevant requirements.
