Quality increase for single-welded joints of thin-walled structures by means of simulation modelling

摘要

The Simulation calculation module and the SolidWorks software package have helped to define the optimal shape and dimensions of single-welded joints which may serve the basis for calculating the process parameters of welding. Having compared the models with different weld cross-sections the authors have defined that the weld height and width do not significantly affect the stress concentration, and the stress concentration and value mainly depend on the shape of the root bead and the gap size between the welded parts.
