Precision Aluminum Welding: Tips and Tricks for Micro Applications

Learn how to achieve high-quality, hermetic, and mechanically reliable welds
May 2026
By: MARK L. BOYLE

Aluminum is widely used in manufacturing because of its strength-to-weight ratio, corrosion resistance, and excellent thermal and electrical conductivity. But the characteristics that make it so desirable also make it notoriously difficult to weld, particularly at micro scales (<1 mm in joint penetration and weld width). Understanding aluminum’s material properties and how best to manage them is the key to success, no matter what project you’re working on.
