Two=stage inertia welding of anode assembly for X=ray target - involves high spindle speed for heating prior to welding of molybdenum (alloy) stem to niobium (alloy) disc
A steam made of Mo or Mo-based alloys is affixed to a disc made of Nb or Nb-based alloys by firstly preheating the disc in the range 200 degrees to 400 degrees C. The stem and disc are placed in an inertie welding appts. and subjected to a flywheel movement of inertia of from 9 lb ft2 to 19 lb ft2,...
