Beryllium Laser Cleaning Settings

When laser cleaning Beryllium, you must first contrast it with more common metals like aluminum, because Beryllium's exceptional reflectivity sends most laser energy bouncing away, demanding a completely different setup to ensure effective contaminant removal without wasting power. This high reflectivity, unlike the better absorption in denser alloys, means you should start with adjusted pulse durations and slower scan speeds so the surface has time to absorb just enough heat for cleaning, while its lightweight nature allows rapid cooling that prevents warping if you control the overlap carefully. Beryllium's superior thermal conductivity spreads heat quickly across the material, which helps avoid localized damage but requires you to monitor passes closely to prevent overexposure. You also need to watch its brittleness compared to tougher steels, as sudden temperature shifts can lead to micro-cracks during the process. In the end, always end sessions with a cool-down period and inspect for any subsurface stress, since overlooking this can compromise the material's integrity in high-stakes applications like aerospace components.

Power Range

Amplifies damage risk in Pulse Width. Keep low to maintain safety margins.

Spot Size

Same power in a smaller spot creates much higher energy density.

Pulse Width

More power means higher peak intensity. Too much can damage the material.

Pass Count

Using more passes means you can use lower power and still get the job done.
