FAQ

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
