The phenomenon of fume generation from filler metal in a brazing process is well known, and it is said that the fumes will cause an undesirable effect on the health, but the study about fumes concerning brazing has hardly been reported on. The authors tried measuring and analysing of fumse using fume-collecting equipment which was specially designed by the authors. The experimental results were as follows. 1) Among many kinds of filler metals, brass, BAg-4,and Bcup-2 produced comparatively larger amount of fumes in the brazing process. 2) The main constituent of the fumes produced during brazing was zinc in the case of brass and BAg-4,and phosphorus in the case of BCup-2. 3) The shape and size of the fumes were different according to the kinds of filler metals, and the size of the fumes was about 1μ∿10μ.
