The 7-Inch Coaxial DED Head for Internal Cylindrical Cladding is a high-speed reflective deposition head with a four-way powder feeding design, optionally compatible with off-axis wire feeding. Optimized for internal surfaces with diameters ≥180 mm, its circular beam delivers uniform energy distribution and powder utilization exceeding 90%. Ideal for vertical deposition and complex thin-walled components, it produces low-distortion, smooth cladding layers, meeting high-precision, low-heat input internal surface remanufacturing requirements.

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 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. Unlike conventional annular powder feeding systems, the four-way coaxial design provides superior vertical deposition
performance, 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 compon
