How to size welds using SOLIDWORKS Simulation?


The edge weld connector estimates the appropriate size of a weld needed to attach two metal components. SOLIDWORKS Simulation calculates the appropriate weld size at each mesh node location along the weld seam.






select face of sheetmetal body


select face of sheetmetal or solid body









reduces allowable shear strenght for calculation of weld strength







Results list the min, max and mean values along weld seam and they are given per unit weld length. The values listed are

– weld size

– weld throat size

– Joint normal force

– shear weld force

– shear surface normal force

– bending moment



This is a great feature to make sure the welds work .
