The 2-Inch Coaxial Laser Metal Deposition Head combines a reflective coaxial optical design with a dual-channel powder-feeding system that directs the powder stream precisely into the center of the laser interaction zone. Engineered for internal bore laser cladding on components with bore diameters of 50 mm and above, it supports processing depths of up to 1 m for stable and repeatable deep-bore laser cladding.
Its compact coaxial architecture enables consistent powder delivery in narrow and difficult-to-access internal geometries. Controlled heat input limits thermal exposure to the substrate, helping produce high-quality, low-distortion cladding layers while preserving dimensional accuracy, process consistency, and component integrity.
Designed for high-precision internal surface enhancement, localized repair, and remanufacturing, this coaxial powder-fed laser cladding head for deep internal bores is suitable for small-diameter cylindrical and tubular components. For OEMs, repair centers, and system integrators, it provides a practical solution where compact access, long processing reach, and repeatable internal deposition quality are critical.

Q1: What is the minimum internal diameter and maximum processing depth of this 2-inch coaxial deposition head?
A1: This head is specifically engineered for extremely confined internal surfaces with a minimum diameter of just 50 mm (approximately 2
inches), while supporting processing depths of up to 1 meter (≈39 inches). This makes it ideal for deep-bore cladding applications such
as hydraulic cylinder barrels, pipeline interiors, precision small-diameter bores, and remanufacturing of deep, narrow internal components.
Q2: What materials can be deposited with this 2-inch coaxial head for small-bore internal repair?
A2: This head supports a wide range of materials, including iron-based, nickel-based, cobalt-based, copper, titanium alloys, and other metal
powders. It is particularly well-suited for high-precision remanufacturing applications where component integrity, wear resistance, and
dimensional accuracy are critical — such as mining hydraulic supports, power transmission shafts, and thin-walled tubular components.
