HiFIT post-weld treatment improves the fatigue life of welded joints 5 to 15 times. It is a proven, affordable way to make bridges, cranes and machines more durable, both new and existing.
Enhance the fatigue endurance of welded steel structures
HiFIT (High Frequency Impact Treatment) tools perform a peening process that increases the fatigue strength and lifespan of welded steel components. The method belongs to the wider category of post-weld treatments called HFMI (High Frequency Mechanical Impact).
With over 25 years of research and development behind it, HiFIT is a globally recognized technology. Research carried out with our tools is part of numerous industry standards and guidelines, such as the IIW recommendations.
Our premium device, the HFM 21R1-S, has built-in dampers that keep the vibration on the handle down to just 3.9 m/s². Its cooling keeps the tool at a low temperature under varying working conditions, which gives it a long service life with minimal wear.
It is light and ergonomic, which makes it the fastest HFMI tool available, with a treatment speed of 1.36 m/min.
HiFIT operates globally through sales representatives in seven countries and has satisfied clients in more than 20 countries. HiFIT Scandinavia is the authorized seller and service provider in the Nordic region.
We have carried out post-weld treatment projects around the world in many industries, and we work closely with every client to make sure each project succeeds.

Who we are
Engineers with research behind them
HiFIT Scandinavia is part of Pascal Engineering, a structural engineering firm specialized in advanced steel structures. Our team holds PhDs from Chalmers University of Technology, including doctoral research on HFMI treatment of steel bridges.
That means we can take your project all the way, from fatigue assessment and design to treatment and quality assurance.
HiFIT takes part in Swedish research projects that develop guidelines and new applications for post-weld treatment.
LifeExt-2
HiFIT is a partner in LifeExt-2, an implementation project that builds on the knowledge and technical development from the research project LifeExt. It aims to provide technical guidelines on using post-weld treatment to extend the fatigue life of existing welded steel bridges. The guidelines cover prerequisites for applying post-weld treatment, how to apply the method, and verification and quality assurance.
Funded by InfraSweden2030. Partners: Trafikverket (the Swedish Transport Administration), Chalmers, KTH, Swerim, HiFIT, Dekra and Winteria. Duration 2½ years from June 2021.
MIDWEST
HiFIT is a partner in MIDWEST (Mechanized post-weld treatment of welded structures for automotive and cargo applications). The project develops and implements mechanized solutions for important improvement methods, namely HFMI, burr grinding and TIG dressing. The results are relevant for wheel loaders and haulers, loader cranes, forklift and container trucks, and fatigue-loaded chassis components in cars.
Funded by Vinnova FFI – Sustainable production. Partners include Swerim, Chalmers, KTH, Volvo Construction Equipment, Toyota Material Handling, HIAB, Gestamp HardTech, SSAB, ABB, Robotdalen, HiFIT, Weld-Hit and Winteria. Duration 3 years from November 2022.
