The influence of gap filler content, gap filler powder size and clearance of gap on the microstructure of the brazing seam was investigated. The volume fraction of the eutectic plus the intermetallic compound and the number of voids in the brazing seam were used to evaluate the factor. The results show that the content of gap filler affects the microstructure of the brazing seam greatly, while the gap filler powder size and the clearance of the gap have little effect on it.
