Abstract

PURPOSE:To stabilize the brazing quality of an Al material and to prevent defective brazing by using a flux coated brazing filler metals provided with a non-corrosive fluoride flux coating on the surface of the brazing filler metal consisting of an aluminum alloy. CONSTITUTION:The flux coated aluminum brazing filler metal 1 for torch brazing consists of the brazing filler metal e' consisting of 6.8-13wt% Si and the balance Al and the non-corrosive fluoride flux coating c' coating the surface of the filler metal e'. Only the materials (a), (b) to be brazed are first preheated to the temp. lower than the m.p. thereof by a burner flame (a) and thereafter the flux c' coated brazing filler metal 1 is heated by the burner flamed (d) and is thereby melted in the case of brazing the Al or Al alloy member by using such flux coated aluminum brazing filler metal 1. The melt is thereby built up on the brazing point and the brazing is executed.

"Prior Art" A torch brazing method has been conventionally used as one of the methods for brazing Ai or A1 alloy members. The torch bone method uses an oxygen = 7 flame, etc. to uniformly heat the area around the brazing material at a temperature that does not melt it, melting the flux applied to the joint and wetting the surface of the brazing material, and then Similarly, this is a method of joining the covered braze aggregates by melting the brazing material coated with flux and supplying the brazing material.

``Problem to be solved by the invention'' However, the melting point and activation temperature of the flux are different from JIS BA4047 or JIS used as a brazing material.
Since the melting point is close to that of A1 alloy brazing filler metal such as BA 4045, it is a task that requires great skill to simultaneously heat the metal brazing filler metal using a burner required for torch brazing and heating the flux, which is an inorganic powder. there were. That is, in conventional torch brazing, as shown in Figs. 5 and 6, a flux (C) diluted with water is applied to the brazing aggregate (a, b), and the brazing aggregate is heated with a burner flame (d). The wire brazing material (e) coated with the flux (C) diluted with water is then heated to melt the flux and the brazing material almost simultaneously. For this reason, as shown in Fig. 7, a break in the solder (h) occurs in the solder fill (f), and a molten part (g) occurs in the overlying solder aggregate (a).
This has the disadvantage that brazing quality is unstable, and poor brazing is likely to occur.
