Abstract
The present invention relates to a method for welding a hard alloy cutting tool, particularly to a method for connecting hard alloy and tool steel by braze welding in the manufacture of a mechanical turning tool. Silver-based or copper-based welding flux is adopted as braze welding flux to weld the cutting tool; the hard alloy and the steel-based material are connected by welding flux on a soft red copper transition sheet inserted between the hard alloy and the steel-based material in a braze welding mode at the time of braze welding. In the method for welding a hard alloy cutting tool of the present invention, the hard alloy of the cutting tool is welded by braze welding flux tightly attached on the red copper sheet; heat stress generated after welding is effectively absorbed by the red copper sheet in a compensation mode; the phenomena of sheet disengagement and sheet smash after braze welding in the production of the hard alloy cutting tool are effectively decreased. The present invention enhances the rate of finished products in the cutting tool production and the quality of the cutting tool, and prolongs the service life of the cutting tool.
