How to Combine Shell Element and Solid Element in ANSYS

Hello Everybody

I'm currently working on on the tubular weld of joint modeling using ANSYS

Problems that I faced was how to combine elements of the shell (for chord and brace) with solid elements (for weld) so that stress transfer can occur between two elements
one technique that I know is using MPC
is there any among you who has a tutorial about it ..?
please help.....
