Laser Slag & Dross Removal for Stainless Steel Components
Laser cutting can produce precise stainless steel components with complex geometries, but it can also create a secondary finishing challenge.
Depending on alloy, thickness, laser parameters and geometry, components can exhibit dross, slag, oxides, heat-affected material and other surface contamination.
Laser Slag & Dross Removal: Why One Process Doesn’t Always Solve the Problem
Electropolishing can be effective for many laser-cut stainless components, but heavy or tenacious laser-related material isn’t necessarily an electropolishing-only problem.
NEE evaluates the material, geometry, surface condition and desired result to determine which process—or combination of processes—is appropriate.
Multiple Tools. One Objective.
Acid Pickling
Can attack oxides and certain laser-related surface contamination.
Electrocleaning
Provides another method of cleaning and surface preparation.
Ultrasonic Cleaning
Provides additional cleaning capability in small openings, slots and complex geometries.
Electropolishing
Can remove surface material while improving surface smoothness and overall condition.
Before & After: Actual NEE Processing Examples
The examples above show actual NEE processing work. Final results depend on the material, geometry and starting condition.

Complex Geometry Makes the Problem More Challenging
Small slots, holes, channels and closely spaced features can make conventional mechanical finishing difficult or impractical. Process selection becomes especially important when unwanted material must be removed without compromising critical geometry or dimensions.
Don’t Start With the Process. Start With the Problem.
The better question isn’t simply, “Do you want electropolishing?” It is: “What are you trying to accomplish?” NEE can evaluate whether acid pickling, electrocleaning, ultrasonics, electropolishing or a combination makes sense.
More Processes. More Options. One Goal: Get the Surface Right.
