Laser cladding, also known as laser metal deposition (LMD), is a technique for applying a layer of material to a substrate. The coating material is melted onto the substrate’s surface using a laser as the heat source. It is primarily used for surface modification, repair, and enhancement of components to improve their wear resistance, corrosion resistance, and mechanical properties.

Titanova specializes in laser cladding, utilizing state-of-the-art robotic systems integrated with direct diode and fiber-coupled lasers. It provides precise control over deposition, ensuring minimal dilution and maximum adherence to metallurgical requirements. This allows us to deliver solutions with unparalleled quality and efficiency in industrial applications.

How Laser Cladding Works

Laser cladding involves a series of steps to achieve a high-quality coating with the desired surface properties. The key stages include:

  • 1. Substrate Preparation

    The substrate’s surface is first cleaned to remove contaminants such as oils, oxides, and dirt using pre-machining a thin layer of base material off.

  • 2. Material Feeding

    The cladding material, either powders or wires, is chosen based on the desired surface properties, such as hardness, corrosion resistance, or wear resistance. Then, a suitable feeding system like a powder or wire feeder delivers the cladding material into the laser beam's path.

  • 3. Cladding Process

    The laser beam is focused on the substrate, generating a high energy density that melts both the cladding material and substrate layer. This process forms a molten pool where the cladding material mixes with a controlled and thin portion of the substrate.

    As the laser moves across the substrate, the molten cladding material solidifies rapidly. This leads to fine microstructures in the clad layer, enhancing its mechanical and corrosion properties.

  • 4. Post-Cladding Treatment

    After cladding, the newly formed clad layer undergoes inspection for defects such as porosity, cracks, or inadequate bonding. This can be done using visual methods, ultrasonic testing, or X-ray inspection.

    If needed, the surface of the clad layer is finished by machining or grinding to achieve the mechanical surface roughness. In some cases, a heat treatment might also be applied to relieve residual stresses or further improve the clad layer's properties.

Advantages of Laser Cladding

Laser cladding offers several advantages in various industrial applications, including:

Laser Heat Treating

Enhanced Properties

Laser cladding improves the surface properties of components by depositing a layer of material that is harder and more wear- or corrosion-resistant than the base material. This extends the lifespan and durability of components.

This is particularly advantageous in industries that require customized components or prototypes with specific shapes and dimensions. Laser cladding can build up material layer by layer, following a digital design file, to produce parts with intricate features and tight tolerances.


Repair and Restoration

This technique is widely used to repair worn-out or damaged components, extending their operational life and reducing replacement costs. By selectively adding material to worn surfaces or damaged areas, laser cladding restores the component’s original dimensions with enhanced properties. This is particularly valuable for critical parts in industrial equipment, pump, and turbines, molds.
