Engineering-Led Surface Remediation & Certified Welding
Merry Metal Works Ltd is a Canterbury-based engineering business specialising in precision laser surface remediation and certified welding services for industrial asset owners.
We support infrastructure, heavy engineering, dairy processing, and manufacturing environments where substrate integrity, controlled material removal, and maintenance readiness are critical.
Our approach is grounded in practical engineering experience — not just equipment capability.
Our Technical Approach
Laser cleaning is not simply an alternative to abrasive blasting. It is a controlled surface preparation method designed to:
-
Remove coatings, corrosion, and contaminants with precision
-
Minimise substrate damage and profile distortion
-
Reduce secondary waste streams
-
Integrate with inspection, NDT, and recoating workflows
-
Improve control in sensitive or operational environments
We understand that in engineered maintenance environments, surface preparation is part of a wider system — including coating specifications, asset life extension strategies, and consultant oversight.
Our role is to support that system with controlled, repeatable surface preparation.
Industrial Context & Experience
Our background includes experience in high-hygiene dairy processing, structural steel fabrication, and certified welding under New Zealand standards.
This means we understand:
-
Risk management in operational facilities
-
The importance of compliance and documentation
-
Working within engineered specifications
-
The hierarchy of consultants, contractors, and asset owners
-
The practical realities of downtime, containment, and safety
We approach every project with a mindset of collaboration — working alongside engineers, coating inspectors, and contractors to deliver safe, technically sound outcomes.
Validation & Collaboration
We recognise that infrastructure and industrial applications often require formal validation pathways.
LaserTech Cleaning Solutions welcomes structured pilot trials and consultant-supervised evaluations to establish performance parameters specific to project specifications.
Our goal is not to replace engineered processes — but to support them with modern, precise remediation methods.
Why We Exist
We established LaserTech Cleaning Solutions to provide:
-
Higher-control alternatives to traditional abrasive methods
-
Reduced environmental impact in industrial cleaning
-
Engineering-minded problem solving
-
Reliable, certified welding capability alongside surface remediation
As New Zealand industries look to extend asset life and improve environmental performance, we aim to be a trusted technical partner in that transition.
