Laser Cleaning Heavily Rusted Steel
Heavily rusted steel is thick oxide over pits and remaining plate or bar. Working the rust off without wasting the sound metal, judging whether the part is still useful, and watching heat in already thin spots are what a careful pass watches.
What This Video Shows
Short qk6t-WEoF18 shows pulsed laser clearing heavy rust from steel in 28 seconds without grit.
Questions this footage answers
What does this Short show about heavily rusted steel?
The clip is a 28-second pulsed-fiber demo on heavily rusted steel. You see thick oxide leave the face while the steel stays in frame. It is footage proof that contactless cleaning can clear heavy rust, not a timed quote for every pit depth or section thickness.
Why avoid grit blast on steel this heavily rusted?
Heavy rust often hides pits and edges that still need to hold size after the soil leaves. Media blast digs those pits deeper and leaves a profile coating or weld prep may not want. The Short shows the laser path clearing thick oxide while the steel outline stays readable.
Should heavy rust raise pulse energy?
Heavy rust usually wants more controlled passes, not a jump past the steel injury band. Published ns 1064 nm work on carbon steel still puts rust clearing near 1.42–4.26 J/cm² and metal injury near 5.7–15 J/cm². Coupon scrap of the same steel family before you open production stock.
Can I copy this traveler straight onto another heavily rusted part?
Use the Short to see heavy oxide leave the part, then coupon the next piece before production. Pit depth and scale thickness change how many passes you need even when the alloy matches. Match scrap first, especially ahead of rust removal work.
