High-Vacuum Annealing of Ultra-Clean / High Performance Welding Wire

This critical welding wire presented California Brazing with a unique heat treating challenge: the project required vacuum annealing to obtain minimum physical properties without yielding detectable surface contamination or oxidation. To achieve these requirements, we used high-vacuum annealing in the 10-6 Torr Range vacuum level. We used a combination of nickel and cobalt base superalloys, and adhered to ASTM E18, ASTM E10 and ASTM E8 testing specifications. Our customer’s testing requirements included hardness and tensile testing, as well as surface analysis. We provided our client with testing reports, certificates of conformance, and furnace profile charts. When we were certain we had met and surpassed our client’s expectations, we delivered the high-performance welding wire to our client, to be used in turbine and aerospace structural repair applications.
