Fatigue Life Estimation for HFMI-Treated Weldments
In accordance to the recommendations by the international institute of welding (iiw) the fatigue strength of welded steel joints is generally independent from the base material’s yield strength. However, applying post weld-treatments, such as the high frequency mechanical impact (hfmi) treatment, enables an increase of the fatigue resistance using high-strength steels as base material [2].

The international institute of welding (iiw) guidelines do not currently include hfmi treatment methods. However, an iiw proposal for fatigue design of hfmi treated welded joints is currently being developed [19]. The proposed guideline considers the different effects of loading, steel strength as well as thickness and size.
Iiw recommendations for the fatigue assessment of welded structures by notch stress method.
The s/n curves below shown the fatigue properties of transverse stiffeners in s690 in as welded condition and post weld treated with hfmi. These curves are marked by the fat class (allowed design stress for a life expectation of 2m cycles) and a slope. The post weld treatment increases the fat class from 71 up to 140 n/mm² (vertical red arrow).
After the iiw recommendations, now finally the „dast-recommendations“ for hfmi are published - in addition to the eurocode stress relaxation because of variable amplitudes - iiw-factors are even valid with variable amplitudes quality-assurance - just a 100 % visual control is completely enough to assure the quality of a hfmi treatment.

It also considers the extra benefit that has been experimentally observed for hfmi-treated high-strength steels. The recommendations offer proposals on the effect of loading conditions like high mean stress fatigue cycles, variable amplitude loading and large amplitude/low cycle fatigue cycles.

High frequency mechanical impact (hfmi) is a reliable, effective and user-friendly method for improving the fatigue strength of welded structures. The method relies on local modification of critical regions in welded joints. In addition to the modification of weld toe geometry (which is solely what other more traditional methods rely on), hfmi induces high local compressive stresses at critical crack initiation sites which results in substantial enhancement of fatigue strength.

High-frequency mechanical impact (hfmi) has emerged as a reliable, effective and user-friendly method for post-weld fatigue strength improvement technique for welded structures. This guideline presents recommendations on proper treatment procedures, quality control measures and fatigue strength improvement assessment based on nominal, hot spot and effective notch stress methods.

The most significant of fatigue life improvement after the hfmi/pit is the hfmi/pit transverse fillet weld. These treated welds obtained 256 mpa of fat class which is 79 % higher than fat class recommended by the iiw for the transverse fillet weld.
On the other hand, hfmi-indentor should be slanted more toward the base metal than the weld to avoid unintentional crack opening. Moreover, the iiw recommendations for both hfmi-treatment inclination and indentation depth could be extended to cracked structures.
Moreover, the book presents procedures for the fatigue life assessment of hfmi-improved welded joints based on nominal stress, structural hot spot stress and effective notch stress. It also considers the extra benefit that has been experimentally observed for hfmi-treated high-strength steels. The recommendations offer proposals on the effect of loading conditions like high mean stress fatigue cycles, variable amplitude loading and large amplitude/low cycle fatigue cycles.
