日鉄テクノロジー List of Products and Services

This is a groundbreaking new product making its debut in the domestic market. ● It can significantly improve the fatigue strength of welded joints with a simple treatment. By applying UIT treatment to the weld toe after repairing fatigue cracks or to areas where fatigue cracks are a concern, an improvement in fatigue life can be expected. <Mechanism of Fatigue Strength Improvement> By applying ultrasonic vibrations to the weld toe, the following effects can be achieved: 1. Transforming tensile residual stress into compressive stress. 2. Reducing stress concentration. 3. Hardening the surface hardness. ● Since ultrasonic oscillation utilizes magnetostriction, it can perform treatments with stable and powerful power.
