Laser Weld Cleaning
Laser cleaning has two important roles in welding workflows: pre-weld surface preparation (removing rust, oil, mill scale, and contamination from the weld zone) and post-weld cleaning (removing heat tint, weld oxide, and spatter from the completed weld and surrounding area). Both are performed accurately without grinding or wire brushing that can contaminate or mechanically affect the weld.
Pre-Weld and Post-Weld Applications
Pre-weld zone preparation
Removing rust, mill scale, oil, and paint from the weld zone prior to welding. A clean surface improves weld quality, reduces porosity, and reduces post-weld rework. Laser cleaning leaves no residue that could contaminate the weld pool.
Post-weld heat tint removal
Weld heat tint (oxide discolouration) on stainless steel and carbon steel is removed precisely — targeting just the oxidised zone without grinding the weld profile or the surrounding parent metal.
Weld spatter removal
Laser ablation removes weld spatter from the weld area and surrounding metal efficiently and without mechanical contact. No grinding wheel, no wire brush, no risk of work-hardening or mechanical stress.
In-line production integration
Laser weld cleaning is suited to integration into fabrication production lines — automated scanning of weld seams for consistent pre- or post-weld treatment at production throughput.
