ID Laser Cladding Service:
The Smartest Way to Restore & Protect Bore Surfaces
Internal bore components in oil & gas, power generation, and aerospace face the harshest wear conditions imaginable. ID laser cladding is the precision answer — and PMMT delivers it in the UAE and beyond.
ID Laser Cladding Service
What Is ID Laser Cladding — and Why Does It Matter?
ID laser cladding (Internal Diameter laser cladding) is an advanced surface engineering process where a high-powered laser beam is directed inside the bore of a cylindrical component. As the laser melts a stream of metallic powder, a new metallurgically bonded layer fuses onto the inner surface — restoring dimensions, adding hardness, and delivering corrosion resistance that the base material alone could never achieve.
Unlike conventional welding or thermal spray, the laser’s concentrated energy creates an extremely narrow heat-affected zone. This means no distortion, no cracking, no delamination — just a dense, precise coating that becomes part of the component itself.
What Is ID Laser Cladding — and Why Does It Matter?
Every component that comes through our facility goes through a rigorous, stage-by-stage process engineered for precision and repeatability.
Component Assessment
Dimensional inspection, material analysis, and failure-mode evaluation to select the optimal cladding alloy and parameters.
Surface Preparation
Bore cleaning, degreasing, and light pre-machining to expose the base metal and ensure maximum bonding.
Laser Cladding
CNC-controlled laser head traverses the bore, fusing metallic powder layer by layer with precise heat input and overlap control.
Post-Processing
CNC finish machining to exact tolerances, plus NDT inspection (UT, PT, or hardness mapping) to validate the cladding.
Why Industries Choose ID Laser Cladding Over Alternatives
The advantages aren’t incremental — they’re transformational for components operating under extreme service conditions.
- Metallurgical bondTrue fusion with the base material — no peeling, no delamination under pressure cycling or thermal shock.
- Minimal heat inputNarrow HAZ preserves the component’s structural integrity and dimensional accuracy.
- Extreme hardnessAchieve up to 65 HRC with carbide-reinforced alloys — vastly outperforming chrome plating.
- Corrosion resistanceInconel, Stellite, and stainless overlays protect bores from H₂S, CO₂, and saltwater environments.
- Dimensional restorationWorn bores are built back to original spec — or upgraded beyond OEM tolerances.
- Cost efficiencyRestore rather than replace — saving 60–70% on components that would otherwise be scrapped.
- Reduced downtimeFaster turnaround than sourcing new OEM parts, especially for legacy or discontinued components.
- Material flexibilityClad with Inconel 625, Stellite 6, WC/Co, stainless, or custom alloys based on service requirements.

Frequently asked questions (FAQ)
What bore diameters can PMMT clad using ID laser cladding?
PMMT’s ID laser cladding equipment is capable of processing a wide range of bore diameters, from small-diameter precision bores through to large industrial housings. Contact our engineering team with your component dimensions for a direct assessment.
Which cladding alloys are available for bore applications?
We work with Inconel 625, Inconel 718, Stellite 6 and 12, Tungsten Carbide composites, Hastelloy C, stainless steel grades, and custom alloy blends — selected based on your operating temperature, pressure, and corrosive media.
Is ID laser cladding suitable for components already in service?
Yes. In fact, the majority of our ID cladding work is on in-service components that have experienced wear or corrosion. We restore dimensional integrity and apply an upgraded surface — often better than the original OEM specification.
How does ID laser cladding compare in price to buying a replacement?
Cladding and restoring a bore component typically costs 30–40% of the price of a new OEM part — and often delivers superior surface performance. For hard-to-source or discontinued parts, the savings (and lead time reduction) are even greater.
What is the typical turnaround time?
Turnaround depends on component complexity and cladding specification. Simple bore restoration can be completed in days; complex multi-layer applications with full NDT documentation may take 1–3 weeks. We always provide a timeline at the quotation stage.
