Laser Cutting Defects: How to Fix Dross, Burrs and Taper (2026 Guide)
Soft dross, hard dross, burrs, kerf taper and rough striations all trace back to five settings. Real 2026 test data: laser power and focus explain about 84% of dross formation while gas pressure explains only 2.7%, the smallest kerf taper measured was 0.027 mm at a 0.192 degree angle, and air assist left a 200 micron oxide layer where oxygen gave a clean edge. Includes a five-step diagnostic order that avoids wasted tuning time.
