FAQ

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.
