Spot weld on very fine mesh

Hi,

I've tried to connect some parts with spot weld elements in HM. The mesh around these spots is very fine, 0.5mm, but the spot weld has a diameter of 2.5mm. After the analysis, the stress peak is always on the element, wich is connected with the spot weld element but normally, since the weld diameter is 5 times larger than the element's edge length, also the adjacent elements should be directly connected to the weld element. Am I right with this idea?

Regards
