you need a specieal type of welder. aluminum has a much lower melting point then iron or steel. You can try to soder it with lead free soder but i am not sure how well it will hold.
welding aluminum rims is not recommended. the welded area will never be as strong as it was before the crack or break. when you weld the area affected. the metal around it is effectively annealed making it softer than it originally was before welding. most places will not weld a rim for the simple reason of liability. soldering or home repairs are asking for trouble. you have to ask yourself. what costs more. a new rim, your wrecked car after the repair fails or your life if it causes a major accident.
It could be welded, but you never would fix a cracked rim.. It would be hard to balance and you could never trust it not to crack and break while using it. Replace it.
No . . . that would be extremely dangerous.
It is called aluminum welding. Aluminum can be TIG welded, the most common method, or oxy-fuel welded, or stick welded, or MIG welded.
If the rim is welded to the tire, yes. You can change it, but you have to replace both the rim and the tire which will cost a lot. If the rim is welded to the vehicle itself, no. You cannot change it. In either case, having a welded rim is technically illegal in the US if you drive it on the road. If you don't, then it's not a problem
No, rims are very tough. It takes a very hard hit to crack a rim. Installing a wheel weight will not cause a crack.

Yes, it can be welded, depending on the location of the crack. Some radiators are repairablbe, depending on the construction of the radiator. Older style all-brass/copper radiators can be soldered (not welded) if the leak area is accessible and the surrounding metal is strong enough. Some newer style plastic tank/aluminum core radiators can be repaired if the leak is at the joint between the tank(s) and the core, while others cannot. The plastic tanks themselves and the aluminum cores cannot be reliably repaired.
With a tube of aluminum crack fixer.
Usually. yes.
It is possible for the rim to crack inside the tire.
I think you mean wheels but no a 5 lug can not be converted onto a 6 lug
Cracks can be welded and then the head can be resurfaced.
