What is the best timing of adding solder?

1. The solder cannot be directly melted by fire. 2. When welding, the welded base metal should be heated first. When the surface temperature of the weldment is dark red, touch the solder to the opposite side of the heating point (thin tube) or 10mm away from the heating point (thick tube) to see if the solder can If the base material is hot, if it can be blanched, the welding timing is appropriate. Otherwise, the base material temperature has not reached the melting temperature of the solder.

What are the advantages of brazing?

(1) The heating temperature of the brazing process is relatively low, so the deformation of the weldment after brazing is small. At the same time, the influence on the microstructure and properties of the base metal of the weldment is relatively small. (2) The brazing process can be applied to the connection of various metal materials, dissimilar metals, metals and non-metals. (3) The brazing of multiple parts or multiple brazing seams can be completed at one time, and the productivity is high. (4) It is possible to braze extremely thin or extremely thin parts, as well as parts with large thickness and thickness.
