The phenomenon of fume generation from filter metal in a brazing process is well known, and if is said that the fumes cause an undesirable effect on the health, but the study about fumes concerning brazing ha! hardly been reported on. The authors tried to measure and analyse fumes with fume-collecting equipment designed by themselves. The experimental results as follows; 1) Among the many kinds of fillet metals, brass, BAg-4, and Bcup-2 produced comparatively large amount of fumes in the brazing process. 2) The main constituent of the. fumes produced during brazing was zinc in case of brass and BAg-4, and phosphorus in 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 lμ〜10μ.
