Need drop receiver and receiver extension

I have done a lot of welding either fabricating or repairing for myself and others on the farm. But there is no way I would do any welding on a hitch or tow bar. If the weld is too hot or not hot enough it won't be a good weld and the weld can break and the heat can weaken the pieces you are welding together to where they could bend or break. I have seen some really pretty welds fail.
Any welding on hitches should only be done my a professional certified welder.
