Results of the oven test for the nickel plating went fairly well. The heavy plating on the actual weld did not flake off or blister at 650F in an electric furnace. I held the dwell temperature at 650F for 2 hours and used a slow cool down of 30 minutes to room temp. I am relatively happy with the results.
The next step is to prepare an actual tube for nickel plating on Wednesday. AFter that is accomplished I will have to test the tube to see if we have cured the vacuum leaks. If we have cured the weld leaks then the tube will be sent to RACS to be rebuilt.
