For manufacturers of dynamically loaded steel or metal structures:
PIT offers you:
PIT enables you to:
Through material savings (up to 40%) and the resulting reduction of manufacturing, transportation, and assembly overhead.
By deliberately introducing residual compressive stress at critical points in the design, we enable you to increase the FAT class design by a factor of 1.55 – 2.00.
The advantages result in a cost-effective design of component safety without making compromises. You can tailor your approach to your specific challenges and decide whether your product requires an economical increase in component safety and/or a cost reduction by saving material without sacrificing safety.
By separately regulating frequency and pressure, we achieve the optimum impact intensity for the greatest possible result, without the risk of overtreatment. Due to the spring-mounted impact mechanism in the hand-held unit, the user no longer has any influence on the intensity arriving at the component. These advantages result in the large effect of PIT, with maximum reproducibility. Our customers confirm time and again that the introduction of the PIT process is significantly less time-consuming than originally expected.
By reducing material thicknesses, you not only save on the use of auxiliary materials such as welding filler metals and gas, but also through the reduced workload
The reduced weight of your construction also leads to lower transport weights and assembly costs
A significant reduction in Co2 emissions and increase in sustainability
Pneumatic Impact Treatment (PIT) is a reproducible process that intentionally induces residual compressive stresses in critical areas of your components, simultaneously optimizing the geometry at the weld seam transition. As a result, it counteracts the development of fatigue cracks at the formation stage.
In addition to the repeated scientific validation of the HFMI (High-Frequency Mechanical Impact) effect, the University of Stuttgart specifically confirmed PIT’s high level of reproducibility without the risk of over-treatment.

Since 2008, PITEC has rapidly emerged as the global leader in the field of HFMI (High-Frequency Mechanical Impact). Through many years of experience and continuous development, PITEC has established itself as the international leader. In 2018, PITEC was acquired by Hermann Fliess & Co. GmbH .
Fliess is a manufacturer of welding consumables with particular expertise in high-strength steels. With PIT enabling the use of high-strength steels even under fatigue conditions, a unique synergy arises..

The sound level of a PIT application isn’t determined by the PIT device, but by the resonating body of the component being treated. As a rule, the application is no louder than working with an angle grinder.
The construction can be designed according to FAT or FKM recommendations and the required PIT treatment can be specified at the appropriate points using a dash-dotted line. vorgegeben werden.
The first step some of our customers take is to use a general work instruction to replace conventional methods like grinding or TIG dressing with a PIT application.
Through the practical user training, which takes 4-6 hours, users learn everything necessary to ensure correct PIT application with appropriate quality.
In addition to the repeated scientific validation of the HFMI (High-Frequency Mechanical Impact) effect, the University of Stuttgart specifically confirmed PIT’s high level of reproducibility without the risk of over-treatment. This study also confirms that a 100% visual inspection of the treatment track in terms of position and possible residual notches is sufficient.
PITEC manufactures its devices with high-quality components from reputable manufacturers in Germany. The devices are designed for industrial use. Taking the company Trumpf Haguenau as an example, our devices sold in 2009 are still in operation today.
