Abstract
PURPOSE: To economically produce the abrasion-resistant bolt which has high adhesion power and does not cause thermal cracking by inserting and pressure-welding a bolt stem into the mounting hole having the pressure-welding cavity of the upset part produced at the pressure welding pierced in the bottom face of the bolt head part of abrasion-resistant material.
CONSTITUTION: A bolt stem mounting hole 4 which permits the insertion of the upper part of the bolt stem 2 made of carbon steel is pierced in the central part of the bottom face of the bolt head part 1 made of high Cr cast iron. A cavity 5 having the shape of approximately the same sizes as the diameter and height of the upset part produced at the top end of the stem 2 at the friction pressure-welding is provided in the deep part of the hole 4. A square recess 6 of which the length of one side is the same size as the diameter of the stem 2 is formed to the contact face of the cavity 5 and stem 2 and the stopper square plate 7 of the square shape of the same material as that of the stem 2 is inserted into this recess 6. Next, the upper part 2a of the stem 2 is inserted into the hole 4 and with the top end face being held contacted to the square plate 7 in the deep face of the cavity 5, the hole 4 and stem 2 are friction pressure-welded while they are being relatively rotated, whereby the abrasion-resistant bolt integrally bonded with the head 1 and stem 2 is produced as shown in the figure.
