Hairline Crack can it be welded

[buzz57]

CAN IT? Yes it can. It will NOT pass any safety inspection anywhere in North America. Welding on the wheel web is illegal and as mentioned dangerous. Why did it crack? Usually due to improper torquing of the wheel. A loose stud will cause it to flex starting the crack process. Cracks start due to flexing, not load or loading of a vehicle.
Bite the bullet and replace the wheel. As an aside, check the mate to it if it's on the back. chances are that it will also show signs of wear. A rust streak coming from a wheel nut is usually a sign of a loose lug nut.Aluminum wheels are more forgiving of loose lugs in that they will wear at the lug mating surface rather than cracking but even they will eventually.

If it's cracked where the lug nut meets the rim replace the rim. Like it has been said, it cracked for a reason.

I weld all kinds of metal. do it daily. i could weld the wheel and make it look like it never happened guaranteed! But it will break again and someone could get hurt. A steel wheel would be possible but i would just buy a new wheel for the amount it would cost.

A sensible, logical explanation. Well done.

The crack goes further then the naked eye can see. I would not weld but replacement is in order!!

buy a new wheel your life is worth alot to someone

Buy a new wheel.

Have them mount one of your old tires on the cracked wheel and keep it as a spare if you have someplace to keep it.
