If you find a good welder in your area, that can weld aluminium it would be ideal/great..But Thats cast and its not going to hold together..JB is the way to go, or replace the basket all together.Cast is used to keep the weight down and cheap to keep the cost down for the builder as well.You need to make sure you clean all that paint/coating off down to surface cast, and clean with alcohol(removes any oils and dust/debris,and dries fast) for a clean adhere surface,or it wont last,or serve justice.I have worked in several Clean Rooms, and they generally use alcohol and hot water to clean everything before entering,even tools.
