Patent abstract
In a conventional wave soldering bath, the bottom surface of a bath body in a position which is below the inlet of a duct underwent erosion by molten solder and had a hole formed therein, causing molten solder to be spilled out from the hole. The cause of erosion of the bottom surface of the bath body is a vortex (T) of molten solder formed below the duct inlet accompanying rotation of an impeller pump (10), and the vortex rubs the bottom surface of the bath body.
