Hopefully you will not experience the possible fate of, when they re-weld such thin Aluminum they will be unsuccessful The heat effected area around the crack is not very forgiving and can recracks quickly from vibration. That is why I would not accept a welded repair on our recent Cacked Charged Air Cooler problem on our '01 Intigue.
Good Luck that you do not experience such reassuring misfortunate.
