The use of carbide welding blade points


1. The welding cutting tool structure should have enough rigidity

Adequate rigidity is guaranteed with the maximum allowable dimensions and the use of higher strength Stainless Steel Casting Parts grades and heat treatment.

2.Carbide blades should be firmly fixed

The cemented carbide welding blade should have a sufficient degree of firmness. It is guaranteed by the sipe and welding quality. Therefore, the shape of the blade insert must be selected according to the shape of the blade and the geometry of the tool.

3.Carefully check the arbor

Before the blade is welded to the shank, the blade and shank must be inspected. The first step is to check that the blade support surface cannot be severely bent. The hard alloy welding surface must not have a severe carburized layer. Carbide should also be used. The dirt on the surface of the blade and the arbor insert groove is removed to ensure reliable welding

4.The rational choice of solder

In order to ensure the welding strength, suitable solder should be selected. During the welding process, good wettability and fluidity should be ensured, and air bubbles should be eliminated so that the welding and the alloy welding surface can be in full contact with each other, and there is no lack of welding phenomenon.

5.The correct choice of welding flux

Industrial borax is recommended. Dehydration should be performed in the drying furnace before use. It is then milled and sieved to remove mechanical debris.s

6.Use mesh compensation gasket

When welding high-titanium and low-cobalt fine-grain alloys and welding long and thin alloy inserts, in order to reduce the welding stress, it is recommended to use thin sheets with a thickness of 0.2 - 0.5 mm or mesh-compensated spacers with a mesh diameter of 2 - 3 mm for welding.
