AN INVESTIGATION ON RIVETING METHOD BY HIGH-FREQUENCY INDUCTION HEATING

Abstract

For investigating riveting methods by using high-frequency induction heating (IH), a series of experiment was conducted. In the proposed methods, rivets were heated by IH before or after inserting into holes in steel plates. The temperature required for riveting could be achieved by the proposed methods. However, the temperatures were relatively low when the rivets were heated after inserting into holes in steel plates. Therefore, phase transformation and work hardening did not proceed sufficiently in these heating methods. Although the shear strengths of rivets heated by these methods were lower by 20 % than that of conventional coke heating method, the shear capacity based on yield stress was satisfied.
