Welding aluminum presents some unique challenges compared to welding steel or other common materials, particularly in terms of the chemistry and crack sensitivity.In many cases, welding aluminum requires following some special procedures. Important factors when welding the material include: selecting the right filler metal; proper storage and thorough cleaning of the base material; and proper welding techniques. 

Aluminum and aluminum alloy welding wire ER4043
