Second step, processing rigid alloy blade, processes the wedge structure of thickness direction at tail end;
The 3rd step is installed carbide chip on matrix, wedge structure is inserted in the locating slot of matrix, and when insertion, the straight flange of wedge structure is close to the solder side of matrix column, firmly carbide chip is pressed in locating slot;
The 4th step, solubilizer, scolder, high-frequency heating welding;
The 5th step, links together two semicylinders with screw.
Further, while carbide chip being installed on matrix, inner cylinder face is provided with locating bar, and the diameter of locating bar is identical with the diameter of carpenter's auger, and carbide chip contacts with locating bar.
Further, the electric current 1450A of high-frequency welding, maximum temperature is controlled at 900 ℃.
Preferably, Suppression of High-frequency Welding Devices is HFP-[15B (C), 20D (E), 35A].
The present invention can make blade on matrix, locate exactly, when guaranteeing blade at high-temperature heating and adding scolder, is not subjected to displacement, and improves the quality of products, and increases substantially product percent of pass, and product percent of pass is increased to more than 98% by original less than 10%.
