What would be the suggested method of making this weld connection, that is to weld the 50mm edge of the RHS to the top end open end of the 90mm SHS ? Is it best to weld a section of plate/flat bar on the end of the 90mm SHS and than fillet weld the rafter on top of that or is notching a portion out of the the 90mm SHS for the 150x50RHS to rest, similar to a half lap joint just as good?
