The Annular Beam DED Head for Internal Cylindrical Cladding is a high-speed reflective deposition head featuring annular powder feeding, with an optional off-axis wire feeding system for wire-based cladding. Designed for internal surfaces with diameters ≥180 mm, its circular beam provides uniform energy distribution and powder utilization ≥90%. Compatible with complex-shaped components, it produces low-distortion, smooth cladding layers. Supports stainless steel and hot-work tool steel deposition, delivering precise internal surface reinforcement and remanufacturing solutions.

Q1: What is the minimum internal diameter required for using this annular beam DED head?
A1: This internal cladding head is specifically designed for internal surfaces with a minimum diameter of 180 mm (≈7 inches). The annular beam
design provides uniform energy distribution around the circumference, making it ideal for refurbishing hydraulic cylinder barrels, pipe
interiors, and mining bore components. For diameters smaller than 180 mm, please contact our team to discuss alternative solutions.
Q2: Will internal cladding cause distortion or heat damage to my cylindrical component?
A2: No. The annular beam design delivers uniform energy distribution with optimized heat input control, producing low-distortion and smooth
cladding layers even on thin-walled cylinders. Combined with high-efficiency water cooling and real-time temperature monitoring, this head
minimizes thermal stress — critical for maintaining dimensional tolerances on high-value components like hydraulic pistons, mill rolls, and
drive shafts.
