We Change the World of Welded Steel Structures: HiFIT Excellence
High Frequency Impact Treatment (HiFIT) is a reliable, effective and user-friendly method for improving the fatigue strength of welded structures. The method belongs to a category of post-weld treatment methods aka high-frequency mechanical impact (HFMI), that involves localized modification of critical regions in welded joints. Beyond modifying weld toe geometry, HiFIT induces high local compressive stresses at critical crack initiation sites, substantially enhancing fatigue strength.
Material hardening process, resulting from the cold-working of steel during HiFIT treatment, further increases the material's resistance to crack initiation. This in turn prolongs the service life of the treated structures.
HiFIT has evolved into a well-established technique and is now widely utilized across various industries. Design regulations, workmanship standards, and quality assurance protocols are detailed in recognized standards and guidelines, such as IIW-recommendations and AASHTO standard.
APPLICATION
A Technology Suited for Manual and Automated Application
HiFIT treatment offers the flexibility of manual or automatic application. For instances where serial production is prevalent, we have developed an advanced robotic solution, representing a state-of-the-art automated application. This robotic approach proves to be an ideal choice, ensuring precision and efficiency in line with the demands of high-volume manufacturing processes.
