Why are Aluminum Welds Weak?

Technology News

(1) The coefficient of linear expansion of aluminum and aluminum alloys is about twice that of carbon steel and low-alloy steel. Aluminum solidification volume shrinkage rate is larger, the deformation and stress of the welded parts, therefore, the need to take measures to prevent welding deformation. Aluminum welding pool solidification is prone to shrinkage, shrinkage,…
