The Coaxial Wire-Fed DED Head for Internal Cylindrical Cladding is a high-speed reflective deposition head featuring an off-axis wire feeding design, optimized for internal surfaces with diameters ≥180 mm. With material utilization up to 100% and no powder loss, it delivers excellent vertical deposition performance and highly stable cladding quality. The system produces low-distortion, smooth surface finishes while offering outstanding cost efficiency with welding wire materials.
It is especially suitable for copper-based, aluminum-based, and titanium-based alloy deposition, supporting a wide range of hardness requirements and diverse industrial cladding processes for internal surface enhancement and remanufacturing applications.

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.
