Just grind of the chrome where you are welding, inner portion of the rim if the ring sits in there, you will be fine. I have read where people say to weld them in sections so it dont worp the ring BS I welded mine right around the rim continues as long as the duty cycle would allow me too, ( I tacked it into postion 1st). No problems at all no leaks and my rig has been sitting since May and havent moved and still no leaky. Good luck let me know if you need a hand
