Here is one example.

Welding weakens a wheel, said Marvin Bozarth, a technical consultant to the Tire Industry Association. "The wheel is designed to operate at certain temperatures, and sometimes when you weld on it, the metal hardens and causes fractures that may not be visible," Bozarth said. Such damage can lead to the wheel failing.

"Don't weld them; don't hit them with a steel hammer," Bozarth said. "You've got to treat them nice and make sure they're in good condition."

Yet despite such warnings, some wheel welding does go on, Bozarth said. "I see it on some wheels," he said, surmising the practice continues to be performed by "people who are just not informed, don't listen, or they think they know better."

He added, "That's what gets people killed."

I stated and I stick by the statement welding on wheels is not good practice (best left to pros) Also these clips are made from hardened steel, welding on them will soon lead to them breaking off at the HAZ (heat-affected zone) in order to manage this process you need post weld treatment (heating the wheel) again not best practice, and a crap shoot for a non-professional at best. In addition any welding or heating of wheels calls for the removal of tubes and tires. Why bother with all that just drill and use some attachment hardware.
