We are leaders in the market for providing best range of Weldments, rolled rings, Rolled Cylinders and Machining


At Millerbernd, our approach to complex weldments is based on the same commitment to innovation and quality that drives all of our manufacturing processes. Millerbernd welders are American Welding Society(AWS) and Canadian Welding Bureau (CWB) certified and can perform various MIG (GMAW), TIG (GTAW), and SMAW welds allowing us to manufacture some of the most complex weldments. After completion, welds are inspected by our in-house staff of American Society for Nondestructive Testing (ASNT) Certified NDT Technicians to ensure our products’ quality.

rolled rings

Millerbernd fabricates rolled rings out of bars, rather than cutting rings out of plate. This reduction in costly waste and extra material handling allows us to deliver products with short lead times and lower prices to our customers. After rolling our rings; we flash-weld, stress relieve, size, flatten, and sandblast your product. We can also machine each rolled ring to your specifications. Our flash welding process ensures every ring receives a 100% full penetration weld without the use of fillers or flux resulting in a near seamless rolled ring. With our unique process we can form, weld, and machine carbon steel rings along with: stainless steel, aluminum, nickel, and other exotic alloys. Rolled Ring Capabilities ¼ up to 5-inch thick bar rolled the “Easy Way” or “Hard Way” Diameters from 6 to 120+ inches Flash welding from ½ up to 24 square inch cross sections Custom CNC machining Rough machining of all surfaces up to 120-inch diameter Faro Arm Inspection Reports

Rolled Cylinders

Our experienced craftsmen form rolled cylinders on machines designed and built by Millerbernd. We begin fabrication by processing raw steel plate in-house. Plates are then rolled into cylinders on pinch rollers or high-tonnage bulldozers. After rolling, cylinder seams are welded with a 100%, full penetration weld. Finally, each cylinder is stress relieved, checked for perfect size and roundness, blast cleaned, and can then be machined or welded as part of a complex weldment based on your specifications. Rolled Cylinder Capabilities Diameters from 7 up to 144+ inches Single-piece construction of plate widths up to 120-inches Wall thickness from ¼ up to four or more inches Machining of interior and exterior surfaces Custom drilling and boring
