I'm really surprised to find that alot of welders are not aware of the fact that you need to preheat aluminum before welding it.
The main reason for this is because of the moisture content of the aluminum.
The material is like a sponge. When you preheat the material the moisture is pulled out and it will accept the weld better. Of course the amount of heat needed is going to depend on the thickness of the material.
I'm just touching on this for now. Some of the other members can add info. to this subject if they like.
