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.

Ideal for surface strengthening and cladding repair of cylindrical, tubular, and flat components across various industries:
Mining & hydraulic support – External surface reinforcement of cylinder barrels and hydraulic legs in coal mining roof supports.
Steel & metal rolling – Wear-resistant cladding for mill rolls, backup rolls, work rolls, and other frequently replaced parts.
Power transmission systems – Surface performance improvement for crankshafts, drive shafts, main shafts, and other rotating components.
Pipeline & energy sectors – External wall protection for pipes used in oil, gas, chemical, and power generation facilities.
Hydraulic systems – Uniform cladding on plungers, sleeves, and tubular parts to ensure sealing reliability.
Flat or partial surfaces – Targeted cladding on localized flat areas or irregular workpiece surfaces.
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.
