Laser cladding is an advanced manufacturing process that is used to improve the surface of metals and other materials. By depositing a thin layer of protective or functional material on to a substrate, the laser cladding technique improves metals resistance to wear, corrosion and heat. It is commonly used in the automotive, tooling and aerospace industries, where materials need to have a long life.
Laser Cladding Classifications
Laser cladding can be classified into several types depending on the laser setup and the way material is deposited. Conventional cladding uses a standard laser beam with moderate power for general applications. Large spot high-power cladding is used for covering larger areas quickly and efficiently. EHLA, or Extreme High-Speed Laser Application, provides very thin, precise coatings at extremely fast speeds. Internal bore cladding is designed to coat the inside surfaces of cylindrical components, such as pipes or engine parts. 3D freeform cladding allows complex shapes and patterns to be coated.
Laser cladding strengthens and smooths metal surfaces, preparing them for further treatments. Laser cladding can also improve parts that will later undergo sulphuric acid anodising, like that by https://www.poeton.co.uk/surface-treatments/anodising/sulphuric-acid-anodising, making sure that coatings stick better and last longer.
How Does Laser Cladding Work?
The process works by directing a high-powered laser beam on to the component’s surface while simultaneously feeding the cladding material. The laser melts the surface and the added material together, forming a metallurgical bond once cooled. This creates a hard, durable layer that sticks strongly to the base material. Laser cladding is highly precise and has minimal heat input, which helps prevent damage and keeps the part strong.
