I'm going to be welding a 5th wheel to a truck frame. Basically, it's similar to what you'd see on a tractor-trailer, just smaller.
The 5th wheel pivots on a mount that's made of 3/8" plate. I'm going to weld it down to a larger piece of 3/8" plate that will be bolted to the frame rails of a diesel-dually cab/chassis set-up (new truck).
Customer does not want any welding to the truck frame itself.
Truck will be pulling a car hauler that holds three cars.
How many bolts, how big, and what grade should be used to bolt the plate to the frame rails?
I'm thinking either 7018 or 7024 to weld the 5th wheel to the plate. The 5th wheel bracket is not factory-beveled, but I'm thinking of beveling it for extra penetration.
The brand new 5th wheel came with no instructions or recommended weld procedures.
