Welding aluminum successfully requires achieving root fusion, but it can be challenging due to aluminum's thermal conductivity. This article outlines five key strategies to overcome these difficulties, including removing aluminum oxide, increasing amperage, and using a helium-argon gas mix. Preheating and selecting the right wire diameter are also critical for successful welds. By following these best practices, welders can consistently attain strong, lasting aluminum joints.
