TY - CONF A1 - Hübner, Martin T1 - Effect of weld design on fatigue strength of welded components using LTT filler materials N2 - The fatigue strength of weld seams was increased by using residual stress-reducing Low Transformation Temperature (LTT) filler metals. Conventional single-layer welded longitudinal stiffeners were welded at the end faces with an additional layer (LTT and conventional welding consumable). The weld geometry was varied by changing the welding parameters. The residual stress reduction determined using XRD depended significantly on the weld geometry. The increase in fatigue strength, on the other hand, was significantly improved in all LTT seam variants compared to conventional single-layer and double-layer layers.
