The Pirates can.....but your in MD. Several of us are union pipefitters by trade and we weld all kinds of metal together.
If your talking about steel wheels and adding the rings yourself, you don;t need to heli-arc it. You can mig it or use a stick welder. Just need to tack the four corners down and then weld it out.
If it's aluminum, then you need a High Frequency machine to heli-arc aluminum.
Stockton Wheels does this type of work for vehicles, so they might do it for ATV wheels......if they can't they can send you into the right direction.

FWIW....why not buy them already installed????
