The Wide Beam DED Head for Internal Cylindrical Cladding features a reflective, off-axis powder-feeding design engineered for high-efficiency internal bore laser cladding on cylindrical components with internal diameters of 200 mm and above. Its wide rectangular beam provides uniform energy distribution across the processing area, helping maintain stable and consistent coverage over large internal surfaces.
Powder utilization exceeds 95%, reducing material waste while supporting alloy coatings across a broad hardness range, including wear-resistant, impact-resistant, and high-strength coatings. The combination of a wide processing beam and precise powder delivery makes the head suitable for demanding internal surface applications where coating uniformity, material efficiency, and repeatable processing quality are important.
In addition to powder-fed DED, the head supports internal surface laser hardening, allowing laser cladding and surface strengthening to be incorporated into the same processing solution. It is suitable for wear protection, impact resistance, localized repair, internal surface enhancement, and remanufacturing of large-bore cylinders, sleeves, pipes, and other cylindrical industrial components.
For manufacturers, repair centers, and system integrators seeking a wide-beam laser cladding head for internal bores of 200 mm and above, this solution combines high powder efficiency, uniform rectangular-beam processing, flexible coating-material compatibility, and integrated internal bore cladding and laser hardening.

Q1: What is the minimum internal diameter this Wide Beam DED Head can access for internal cylindrical cladding?
A1: While exact minimum diameter depends on the specific head configuration, this wide beam DED head is specifically optimized for internal
cylindrical cladding, designed to access confined bore spaces commonly found in hydraulic cylinders, pipe interiors, and mining bushings.
Its reflective off-axis powder feeding ensures a stable powder stream and uniform cladding layer even on deep or narrow internal surfaces.
Please contact our team with your specific bore size for compatibility details.
Q2: What is the powder utilization rate of this internal cladding head, and what materials can it apply to internal bore surfaces?
A2: This wide beam DED head achieves powder utilization rates ≥90% thanks to its reflective off-axis powder feeding design, minimizing waste
— especially critical when working inside expensive components. It supports iron-based, nickel-based, cobalt-based, copper, titanium alloys,
and high-hardness carbide coatings, making it ideal for internal wear protection of hydraulic cylinder barrels, pipe inner walls, and other
cylindrical bores subject to abrasion or corrosion.
