Services that improve the performance and durability of your welded structures.
Post-weld treatment for a wide range of applications and conditions.
We have comprehensive expertise in every aspect of High Frequency Mechanical Impact (HFMI) treatment. This lets us take full responsibility for the entire process, from advanced analysis to execution and quality assurance, and develop technical solutions tailored to each project and client.
We follow the guidelines and recommendations of the International Institute of Welding (IIW) and AASHTO.
Authorized seller and service provider of HiFIT® in Scandinavia.
HiFIT Scandinavia is the authorized distributor of HiFIT® equipment and services in Scandinavia. The HiFIT device is compact and robust, which makes it suitable both in the workshop and on site.
The handheld, pneumatic device needs a compressed air supply of 6–8 bar and at least 250 l/min. It needs no external electrical power, and the intensity is set with an adjustment mechanism to suit the material being treated.
Quality assurance according to the IIW recommendations.
We follow the "IIW Recommendations for the HFMI Treatment" from the International Institute of Welding, as well as AASHTO. Quality assurance of the treatment is carried out both qualitatively and quantitatively. The welded details are inspected visually before and after treatment, to confirm that the detail is suitable and that the treatment was carried out well.
Local weld geometry is then measured to verify the treatment. A minimum indentation depth of 0.1–0.2 mm indicates correct HFMI treatment. Depending on the project, we measure with gauges, imprint materials or laser scanning.
Complete solutions for optimizing the design of welded steel structures.
Optimization usually starts with a thorough analysis of the existing design to identify hot spots, with a focus on fatigue-critical details. This may lead to proposals for a better design, including improved detailing early in the design stage.
We then propose a plan for post-weld treatment of the details that govern the design, taking into account the type of structure, the details, the loading and the required design life. Detailing, material selection and production aspects are adjusted step by step until a set target, such as weight or total cost, is reached.
Training and certification tailored to your needs.
Just like welding, post-weld treatment is a specialized process that should only be carried out by trained, experienced people. To get the full benefit of the treatment, the structure must also meet several technical requirements, such as weld quality and accessibility.
We offer courses and training sessions, on-site technical supervision and support, and service and support contracts customized to each client.
Consultation in finite element modeling, material science and structural assessment.
We offer advanced technical solutions at the forefront of research. Our researchers and engineers have long experience and state-of-the-art knowledge in advanced finite element modeling, material science, design and optimization, programming and structural assessment of steel structures.
