Beyond the Bead: The Science of Minimizing Porosity in Aluminum Laser Welds

Introduction: For mission-critical components in the aerospace and semiconductor industries, a weld that “looks good” on the surface isn’t enough. Internal porosity—microscopic gas bubbles trapped within the weld—can lead to structural fatigue and vacuum leaks. The Technical Challenge: Aluminum’s high affinity for oxygen leads to the rapid formation of an oxide layer ($Al_{2}O_{3}$), which traps […]
