Huh???? What the hell did you say? So, did the rocket ever take off?Hardfacing has various applications sounds like you were cladding Wear plates for abrasion. I worked at a place called PJ Valves that did work for the NAVY. We would apply Stellite #6 which is a Cobalt Based material (Rockwell of 38-42C) into a machined groove on Valves or Discs. Both parts were then finish machined and were Dye Penetrant tested to check for Porosity. We did most of it using a Mechanized (PTA) Plasma Transferred Arc machine which worked well. We also had procedures for both Oxy-Acetylene and TIG Processes. We did a lot of Carbon Steel Globe Valves, Chrome Moly Components and some Stainless Steel Gate Valves.
