What should be the surface contact type between two parts to be welded?
The image above is the cross-section of my model.
It has several parts, which are held together by two fillet welding (pointed by red arrows).
The cross-section of the fillet weld is a right-angled triangle whose vertical and horizontal sides have bonded contact type with other parts that are to be welded together.
What should be the contact type of the parts to be welded together (say for instance pointed out by blue arrows) ??
Intuitively I am thinking that it should not be bonded type since in the real world it has either frictional or rough contact.
So while doing the simulation, what is the contact type I should choose between the parts which are to be welded together?
I am looking forward to hearing from any one of you.
