Effect of curvature of convex and concave planes on the fillet size formed after brazing of aluminum was investigated in relation to the brazing method. The fillet size was measured by throat thickness and vertical leg length on the inside (concave plane) and outside (convex) plane of an aluminum pipe braze specimen. Fillet size estimated by the Laplace equation was larger on the inside than that on the outside. In vacuum brazing inside fillet was larger than outside one under limited test conditions, while in dip brazing inside fillet was always larger than outside one, which agreed well with the prediction of the Laplace equation. The discrepancy between the calculation and experimental results in vacuum brazing was attributed to the poor flowability of molten filler metal
