However, laser welding of high-strength aluminum alloys at high welding speeds may result in the formation of transverse hot cracks in the weld seam, potentially causing component failure due to leakage. To determine strategies to avoid transverse hot cracks, the influence of the welding speed during full-penetration laser welding is analyzed both experimentally and theoretically using numerical simulations of the temperature field and the fluid flow. A metallographic analysis of the welded samples showed an increase in the number of transverse hot cracks with increasing welding speeds. The results revealed that a major mechanism for the formation of transverse hot cracks at high welding speeds is a significant reduction of the static pressure at the side of the melt pool, which impairs liquid feeding into the intergranular region.

However, laser welding of high-strength aluminum alloys at high welding speeds may result in the formation of transverse hot cracks in the weld seam, potentially causing component failure due to leakage. To determine strategies to avoid transverse hot cracks, the influence of the welding speed during full-penetration laser welding is analyzed both experimentally and theoretically using numerical simulations of the temperature field and the fluid flow. A metallographic analysis of the welded samples showed an increase in the number of transverse hot cracks with increasing welding speeds. The results revealed that a major mechanism for the formation of transverse hot cracks at high welding speeds is a significant reduction of the static pressure at the side of the melt pool, which impairs liquid feeding into the intergranular region.

These cracks are initiated as a result of thermal deformation, the decrease of the static pressure in the melt pool and the shrinkage during solidification. Particularly, this affects alloys of the 6000 series with elevated concentrations of the alloying elements silicon and magnesium. In [1], authors have demonstrated that applying external mechanical compressive stresses during welding reduces the formation of transverse hot cracks due to an increase of the static pressure in the melt pool. However, since such compressive stresses cannot always be applied externally, it would be desirable to induce these stresses within the sheet metal material. Against this background, near-surface embossing [2] was used in the present study to induce compressive residual stresses in sheet metals. Simulations were first carried out to examine the effects of varying the distances between the embossed patterns and the weld seam area to determine whether the compressive stresses affect the welding zone. Subsequently, several configurations of embossed sheets were produced, analyzed and welded. Finally, the resulting hot cracks were analyzed using metallographic sections and the results were compared with unembossed welded samples. The comparison of embossed and unembossed samples revealed the amount of residual compressive stresses and thus the formation of hot cracks can be reduced depending on the distance and design of the embossing pattern.

However, their susceptibility to transverse hot cracking during laser welding at high welding velocities is challenging. This study investigates the mechanisms of transverse hot crack formation by means of numerical simulations of the temperature field and melt flow in the melt pool and validates the results with experiments. The results reveal a critical zone at the side of the melt pool which is characterized by a high static pressure drop at the liquidus isotherm as a result of high melt flow velocities and cooling rates, which affect the intergranular melt flow during solidification. The study provides valuable findings, which enable the optimization of high-speed laser welding of aluminum alloys, to avoid the formation of transverse hot cracks.https://puma.ub.uni-stuttgart.de/bibtex/2b357d5772d11474e079011ef5a7b594c/ifswifsw2025-07-07T14:39:44+02:00myown Welding Simulation Cracking MacroMaterialProcessing Aluminium <span data-person-type="author" class="authorEditorList "><span><span itemtype="http://schema.org/Person" itemscope="itemscope" itemprop="author"><a title="Johannes Michel" itemprop="url" href="/person/13bd32eab7941897d45cf2e73a769eeb4/author/0"><span itemprop="name">J.

However, their susceptibility to transverse hot cracking during laser welding at high welding velocities is challenging. This study investigates the mechanisms of transverse hot crack formation by means of numerical simulations of the temperature field and melt flow in the melt pool and validates the results with experiments. The results reveal a critical zone at the side of the melt pool which is characterized by a high static pressure drop at the liquidus isotherm as a result of high melt flow velocities and cooling rates, which affect the intergranular melt flow during solidification. The study provides valuable findings, which enable the optimization of high-speed laser welding of aluminum alloys, to avoid the formation of transverse hot cracks.https://puma.ub.uni-stuttgart.de/bibtex/22a6819248e2bec9f5501fe6a7ed724f4/annettegugelannettegugel2025-07-07T09:35:54+02:00Agent-Based Cars Charging Demand Electric Grid Level Location-Dependent Mobility Passenger Regionalization Simulation Square Using an at of the <span data-person-type="author" class="authorEditorList "><span><span itemtype="http://schema.org/Person" itemscope="itemscope" itemprop="author"><a title="Nelly-Lee Fischer" itemprop="url" href="/person/19db81b05e4245d97297f51e5d150705f/author/0"><span itemprop="name">N.
