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.
