Course of the action:
The impact intensity of the HiFIT device is to be calibrated acc. to the material and to the pressure of the air supply prior to use. The calibration is to be checked by…
Practical Significance of the IIW Recommendation
The application of the IIW recommendations results in excellent improvements against weld fatigue for three different seam types.
Here are the…

The same weld construction is now from a steel fy ≥ 950 MPa. Will this not be treated the as welded status will not be changed and stays with a FAT Class of 63 (Fig. 9). There is no…
The effectiveness of the peening results from the combination of the geometric (inside rounding), and the mechanical (work hardening), and the strain (residual compressive stress) aspects. The…
