Porosity-Controlled Laser Welding for Mission-Critical Aluminum Components

In aerospace and semiconductor manufacturing, a weld that looks flawless on the surface may still conceal critical internal defects. Microscopic gas pockets—known as porosity—can reduce fatigue life, compromise structural integrity, and create leak paths in high-vacuum assemblies. The Technical Challenge Aluminum reacts rapidly with oxygen, forming a persistent aluminum oxide layer (Al₂O₃). This surface layer […]
