Overview of HiFIT Technology
HiFIT in Germany focuses on the research and production of high-frequency impact treatment equipment, with its core technology belonging to the field of spray coating technology. It is mainly used to optimize the fatigue strength of welded steel components and extend their service life. By adopting HiFIT post weld treatment technology, the fatigue performance of welded joints can be improved while balancing economy and practicality, helping to enhance the cost-effectiveness and operational stability of the structure throughout its entire lifecycle. After more than 25 years of technological accumulation and R&D iteration, HiFIT related technologies have accumulated extensive application cases and industry recognition worldwide.
High frequency impact treatment (HiFIT), as a convenient and stable welding structure strengthening method, belongs to the high-frequency mechanical impact (HFMI) post weld treatment method. Its core is to locally optimize the key areas of the welded joint. This process can not only adjust the front geometry of the weld seam, but also generate high local compressive stress at key locations where cracks are prone to occur, thereby optimizing the fatigue strength of the welded structure.
During HiFIT processing, steel undergoes material hardening through cold working, which further enhances the material's resistance to crack initiation and helps extend the service life of the treated structure.
HiFIT's main products
The core products of HiFIT include HFM 21R1-S, HFM 12P1, and HF 08-30. Among them, HFM 21R1-S, as an upgraded product, has undergone multiple optimizations in performance and design. The following is a detailed introduction to this model.
HFM 21R1-S series handheld high-frequency impact welding gun
The HFM 21R1-S is an upgraded iteration of the HFM 12P1 model, which has been in use in the international market for over fourteen years and has accumulated rich application experience.
The new HFM 21R1-S HiFIT equipment adopts a structural decoupling design, effectively reducing the vibration amplitude at the handle. When the operator guides the equipment along the weld seam, they can obtain a more comfortable operating experience. The device handle adopts ergonomic design, and auxiliary handles are added on both sides of the hammer shaft to further improve operation convenience. The acceleration value at the handle can reach 3.9 m/s ².
The pin of the device can still be replaced without tools, and a new locking device has been added to effectively prevent accidental loosening of the pin, balancing the convenience and safety of operation.
Based on the requirements for device size in practical application scenarios, the overall length of HFM 21R1-S has been shortened from 288 millimeters to 225 millimeters, making it easier to operate in small spaces. In addition, the corner heads equipped with the equipment are compatible with both HFM 12P1 and HFM 21R1-S models, and can reach difficult to handle parts in the welded structure.
The adjustment unit at the end of the hammering mechanism is used to set the impact strength. The equipment is equipped with 10 levels of scale markings, and the operator can intuitively read the preset impact strength parameters for precise adjustment.
