Can You Tap a Deep Through Hole from Both Sides?

When a through hole is too deep for a standard tap, machining halfway from each end may seem like a practical solution. However, the most important question is not simply whether the tool can reach the required depth. It is whether the finished component needs two independent threaded sections or one continuous internal thread. Tapping […]

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 […]
