About HiFIT Vertriebs GmbH
HiFIT Vertriebs GmbH, based in Braunschweig, offers the HiFIT method – a high-frequency impact treatment (HFMI) for the post-treatment of weld toe transitions. Local plastic deformation produces compressive residual stresses which, according to the company, increase the fatigue strength of dynamically loaded welded structures by 80 to 100 percent and extend service life. The company has focused on holistic solution concepts for extending the service life of welded steel structures: it distributes the HiFIT devices (HFM 12P1, HFM 12P1-B, HFM 21R1-S) developed by DYNATEC Gesellschaft für CAE und Dynamik mbH, as well as attachments and spare parts, exclusively worldwide. In addition, HiFIT Vertriebs GmbH offers weld seam post-treatment as a contract service, including the refurbishment of existing structures, as well as training for operators and supervisory personnel. For consulting, including FEM simulation and engineering calculations, the company cooperates with DYNATEC. Materials processed are mainly structural steels and higher-strength fine-grained steels such as S355J2, S460N and S690QL. Application fields include structural steelwork, press manufacturing, power plant engineering and process engineering.

Materials and Processes
HiFIT method (High Frequency Impact Treatment)
High-frequency hammer peening method for plastic deformation and work hardening of the weld toe transition; increases the fatigue strength of dynamically loaded weld seams.
S355J2
Structural steel for which the effectiveness of the HiFIT post-treatment has been experimentally demonstrated.
S460N
Fine-grained structural steel whose use becomes economically more attractive through weld seam post-treatment.
S690QL
Higher-strength quenched and tempered steel; higher strengths increase the effectiveness of the HiFIT treatment.
Higher-strength fine-grained steels
Even higher-strength steels can be treated particularly effectively, among other things for weight-optimized designs.
