The influences of strength matching on fillet weld were analyzed. The relationships among fillet weld size, thickness of base metal and matchingcoefficient of strength were established.
The recommendation values of the matchingcoefficient of the separation spaces and the length of the cylindrical section weere proposed for the hydrocyclones in different technological situations.
