Bonded Contact and Plasticity

Hi,

I was trying to model a frame where the beam is welded to the column by groove weld. I modeled the beam and groove weld using a shared topology and connected the beam and weld to the column using bonded contact, but I recently saw a post Here that said bonded contacts should not be used where plasticity is expected. Can anyone please elaborate on this matter and when to use bonded contact with material non linearity?

Thanks
