Our Methodology
At Merry Metal Works, our laser cleaning process is designed to deliver precision surface remediation while maintaining the integrity of the underlying material.
We combine controlled laser technology with a structured approach to ensure consistent, repeatable outcomes across a range of industrial and infrastructure applications.
Assessment & Scope Definition
Each project begins with an on-site or documented assessment to determine:
-
Type and extent of contamination (corrosion, coatings, grease, etc.)
-
Substrate material and condition
-
Required level of removal (cleaning vs full coating removal)
-
Access, safety, and environmental considerations
This allows us to define the appropriate methodology before work begins.
Process Selection & Calibration
Laser parameters are carefully adjusted to suit the application, including:
-
Energy intensity
-
Scanning parameters
-
Surface interaction level
This ensures:
-
Effective removal of contaminants
-
No unnecessary substrate damage
-
Controlled, consistent results
Surface Remediation
Laser cleaning is carried out using a non-contact process that removes unwanted material without abrasive media or chemicals.
Key outcomes:
-
Targeted removal of corrosion and coatings
-
Preservation of base material integrity
-
Minimal disruption to surrounding areas
Quality Control & Verification
Throughout the process, surfaces are monitored to ensure alignment with project requirements.
Where required, this may include:
-
Visual inspection
-
Preparation standards for coating systems
-
Compatibility with NDT (Non-Destructive Testing) processes
-
Temperature & surface testing
Completion & Reporting
Upon completion, we ensure:
-
Surface condition meets agreed scope
-
Work areas are left clean and controlled
-
Documentation or sign-off provided if required
