The invention provides a single-face bonding method suitable for hard alloy strips in a hard alloy hard-face machining process and application. A locating groove plate for bonding is scientifically designed, the hard alloy strips are placed on the locating groove plate, the hard alloy strips are bonded through punched single-face adhesive tape, and the hard alloy strips or blocks are fixed through spot welding; and then the adhesive tape is placed on a steel surface of a to-be-machined component, and through spray welding, bead weld and grinding, the steel surface is machined into a hard surface. According to the method, the aim that a large number of hard alloy strips are bonded at a time is simply and easily achieved, the bonding efficiency is greatly improved, and the conditions that due to manual operation, the bonding angles are different, and the bonding intervals are uneven are avoided; the bonding precision is improved, and wear resistance of the product hard surface can be effectively ensured and improved; and the method can be well applied to the aspect of hard-face machining of centering guides or TC bearings of drilling tools or screw drilling tools.
