NDT Surface Preparation
Non-destructive testing works only on a clean, undisturbed surface. Paint, scale, rust, and coating hide the defects your inspector needs to find. Laser cleaning strips the surface to bare metal for penetrant, magnetic particle, and ultrasonic inspection with no metal smearing and no residue. Mobile across NJ, NY, and PA.

Surface-breaking cracks are the defects inspection exists to catch. Grinding and blasting smear soft metal across the crack mouth and close the opening. The inspector reads a clean pass on a part with a live flaw. A missed crack shows up later as a weld failure or a recalled lot.
Chemical strippers and solvents leave a film. Penetrant inspection depends on dye wicking into open defects, and residue blocks the wick and masks indications. Blast media drives grit and dust into the surface and into the flaws under inspection.
Heavy abrasive prep removes base metal and changes wall thickness, which corrupts ultrasonic readings and rejects good parts. Inspection prep needs a clean surface, not a reshaped one.
Why Laser for NDT Surface Preparation
PT and MT Ready
Clean, undisturbed metal for dye penetrant and magnetic particle inspection. No smeared metal closing crack mouths. No residue blocking penetrant wicking.
UT Compatible
No base metal removed, no wall thickness change. Ultrasonic readings stay true. The surface gets clean, not reshaped.
Weld and HAZ Cleaning
Strip mill scale, oxide, and coating from the weld, the toe, and the heat-affected zone. The inspector reads the true condition of the joint.
No Media, No Smear
No grit driven into the flaw. No chemical film over the surface. The defect stays open and readable.
Inspection Documentation
Surface cleanliness verification, Laser Safety Officer report, and before-and-after photos with every job. Built to feed your QA paper trail.
Spot Cleaning Speed
Most inspection prep is a weld band or an inspection window, not a full surface. The laser targets the exact area with no masking and no containment.
How We Do It
The pulsed fiber laser lifts paint, scale, rust, and coating off the surface with no contact. The metal underneath stays at full thickness and the crack mouths stay open. Nothing smears across the defect.
No chemicals touch the surface, so penetrant wicks into open defects with no residue blocking the dye. No blast media means no grit driven into the flaw you are trying to read.
We mobilize to your shop or field site with the laser unit, generator, and HEPA fume extraction. We clean the weld, the heat-affected zone, or the inspection window, and hand off a surface ready for the inspector. Surface cleanliness documentation comes with every job.
