The 7-Inch Coaxial DED Head for Internal Cylindrical Cladding is a high-speed powder-fed directed energy deposition head featuring a reflective optical design and a four-way coaxial powder-feeding system. Engineered for internal bore laser cladding on cylindrical components with internal diameters of 180 mm and above, it supports stable material delivery and repeatable deposition. An optional off-axis wire-feeding module is available for wire-based cladding applications.
Its optimized circular beam profile provides uniform energy distribution, while powder utilization exceeds 90%, helping reduce alloy consumption and material waste. The head is particularly suitable for vertical-position deposition and complex thin-walled components, producing smooth, low-distortion cladding layers while limiting thermal input to the substrate and helping preserve dimensional accuracy.
Designed for internal surface reinforcement, localized repair, dimensional restoration, and remanufacturing, this coaxial laser cladding head for internal bores of 180 mm and above provides a flexible solution for powder-fed DED and optional wire-fed deposition. It is well suited to OEMs, industrial repair centers, and system integrators requiring precise and repeatable internal surface processing for demanding industrial components.

Q1: What is the minimum internal diameter required for this 7-inch coaxial DED head?
A1: This internal cladding head is optimized for internal surfaces with a minimum diameter of 180 mm (approximately 7 inches). The four-way
coaxial powder feeding design ensures precise powder convergence at the laser spot center, delivering uniform energy distribution and
powder utilization exceeding 90% — ideal for vertical deposition and complex thin-walled internal components.
Q2: Can this coaxial DED head be used for vertical internal cladding applications?
A2: Absolutely. The four-way coaxial design supports stable powder convergence and consistent deposition in vertical and non-horizontal
orientations. making it highly effective for internal cylindrical surfaces that require cladding in non-horizontal orientations. This capability
is especially valuable for repairing bore walls in mining hydraulic supports, pipeline interiors, and complex-shaped components.
