Fabricated High Temperature Alloy Consumable Insert for the Nuclear Industry

High Temperature Alloy Consumable Insert
High Temperature Alloy Consumable Insert

At Imperial Weld Ring, we recently demonstrated our ability to manufacture a custom sized product that fulfilled the stringent requirements of a power generation customer. To up the stakes, this high temperature alloy consumable insert was fabricated to rigorous nuclear quality assurance requirements, which even included on-sight inspections and audit procedures. After we designed the tooling, we used our custom-tooled roll formers, wire winders and straighteners, as well as metal shears to draw the 0.156" diameter weld wire per MIL-E-21562D, AM. 7, 1, Type EN/RN62. Spooled to various diameters, the wire was 0.044" wide and 0.150" thick. Then we employed our optical comparator, precision gauges, and testing instruments calibrated to MIL-STD-45662 to inspect the dimensions of the wire, which was finally finished to 63 grit. Subsequently, the wire was fit into a custom shaped profile with precision tolerances of ±0.002 wide by ±0.002 to 0.003" thick and TIG welded. This 500-lb. fabrication was done to ASME SECTION III, NQA-1, 10 CFR 50 Appendix B standards and delivered to this domestic customer in only two weeks.

Imperial Weld Ring refused to shy away from a project like this that had to be done to meticulous quality assurance requirements and nuclear standards. To find out more about us, please contact us directly.
