Snoopy is correct , especially with alloys, normalising is a must as is preheating of a metal that will be put under multi directional loads.
More importantly contact your insurer and ask what is their policy regarding rewelded alloy rims , its a very grey area that can lead to great financial loss and legal issues you just don't need.
Sometimes it's cheaper to just replace the item than go through the unknown.
I scrapped the welded rim , my life , my family and friends lives are more important.
