The Coaxial Wire-Fed DED Head for Internal Cylindrical Cladding is a high-speed directed energy deposition head with a reflective optical design, engineered for internal bore laser cladding on cylindrical components with diameters of 180 mm and above. Its wire delivery architecture achieves up to 100% wire utilization, avoiding powder overspray while supporting stable vertical deposition and repeatable cladding quality. The head produces smooth, low-distortion cladding layers and helps reduce material waste and feedstock costs.
It is particularly suited to copper-based, aluminum-based, and titanium-based alloys, providing a flexible DED solution for non-ferrous alloy deposition across different hardness targets and service conditions. Typical applications include internal surface enhancement, localized repair, and remanufacturing of large-bore cylinders, sleeves, and other tubular components.
For manufacturers and repair centers seeking a wire-fed laser cladding head for internal bore repair and remanufacturing, it combines high material efficiency, stable deposition, low distortion, and broad non-ferrous alloy compatibility.

Q1: What is the advantage of a wire-fed DED head over powder-based systems for internal cylindrical cladding?
A1: Unlike powder-based systems that typically have 10–15% material loss, this coaxial wire-fed DED head achieves 100% material utilization with
zero overspray or waste. This significantly reduces operational costs — especially important when working with expensive copper-based,
aluminum-based, or titanium-based alloys. The off-axis wire feeding also eliminates powder clogging issues commonly found in internal bore
applications.
Q2: What is the minimum internal diameter this wire-fed DED head can access, and does it perform well on vertical surfaces?
A2: This head is optimized for internal surfaces with a minimum diameter of 180 mm (≈7 inches). Its coaxial wire-fed design delivers excellent
vertical deposition performance, producing low-distortion and smooth surface finishes even on non-horizontal internal bore walls — ideal for
repairing hydraulic cylinder barrels, pipe interiors, and mining components in real-world orientations.
