Wie PIT Schäden, Ausfälle und Folgekosten gezielt vorbeugen kann.
PIT (Pneumatic Impact Treatment) is a reproducible HFMI (High-Frequency Mechanical Impact) process for the post-weld treatment of welded joints. It introduces compressive residual stresses and improves the weld toe geometry, significantly increasing fatigue strength and fatigue life.
In addition to extensive scientific evidence confirming the HFMI (High-Frequency Mechanical Impact) effect, the University of Stuttgart has demonstrated the high reproducibility of PIT without the risk of overtreatment.
Die Anwendung von HFMI wird unter anderem in folgenden Regelwerken und Richtlinien berücksichtigt:

PIT System and User Training for One of the World’s Most Exciting Research Environments
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. 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.
