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

Key Advantages of Our Approach

  • Precision-controlled material removal

  • Contaminant containment

  • Built in substrate cooling system & ventilation

  • No abrasive blasting media

  • No chemical waste

  • Reduced cleanup and containment requirements

  • Suitable for sensitive or complex assets
