Laser Cleaning Epoxy Coated Tube
An epoxy-coated tube has a hard film on a round wall. The laser is taking a lasting coating off, so even work around the tube, heat that can soften remaining epoxy, and the thin wall underneath if the beam stays on one line are what matter.
What This Video Shows
Short GH-gd0i-VIA shows pulsed laser clearing epoxy coating from a tube in 17 seconds without grit.
Questions this footage answers
What does this Short show about an epoxy-coated tube?
The clip is a 17-second pulsed-fiber demo on a tube carrying old epoxy coating. You see the epoxy leave the tube face while the tube stays in frame. It is footage proof that contactless cleaning can clear epoxy from tube stock, not a timed quote for every coating thickness or diameter.
Why avoid chemical strip on an epoxy-coated tube?
Chemical strip baths leave disposal burden and can attack thin tube walls when soak times run long. The Short shows the laser path clearing epoxy while the tube outline stays readable for the next coating or weld step.
Can I copy this traveler straight onto another epoxy-coated tube?
Use the Short to see epoxy leave the tube, then coupon scrap that matches the next coating thickness and diameter before production. A copied recipe can mark soft faces when the epoxy is thinner than the demo piece. Match scrap first, especially ahead of coating removal work.
What keeps tube steel safe under epoxy?
Stop once epoxy stops leaving the face, and keep energy under the carbon-steel injury band on coupon scrap. Published ns 1064 nm work puts steel injury near 5.7–15 J/cm², so coating passes should stay below that ceiling while soil is still clearing.
