Description:
<jats:p>The advantages of low‐heat joining, such as low distortion and no appreciable influence on the local material properties as a result of the low heat input, should be utilized for improving the reliability of processes for the manufacture of high‐strength structures. For this purpose, the mutual interactions among the parameters of the joining process, the brazing‐seam geometry, the brazing filler, the type of stress, and the fatigue strength, especially for arc‐brazed structures, are the subject of investigations for estimating the lifetime of locally hardened components by computational methods in the future. Fatigue life tests of brazed specimens show a significant increase of fatigue life compared to laser‐welded specimens. A further increase of fatigue life is expected by optimizing the geometry of the seam.</jats:p>
