| "WE NEED TO JOIN COPPER-MOLYBDENUM TO COPPER BARS OF THE SAME DIAMETER. WE CURRENTLY BRAZE BUT HAVE TROUBLE OBTAINING 100% FILL RATES. WE HAVE LOOKED AT EB WELDERS AND THEY LOOK PROMISING. HOWEVER, WE EXPECT THAT THEY WOULD BE COST PROHIBITIVE. WE WOULD LIKE TO KNOW YOUR OPINION ON WHETHER OR NOT WE SHOULD PURSUE THIS PROCESS." |

| Yes, we do think electron beam welding would be worth looking at for your copper-molybdenum application. Copper + copper alloys lend themselves to EB Welding compared to other welding processes in that electron beam key hole welds can maintain a high depth to width ratio because there are little losses due to conduction, which can be a major problem when welding copper. If you have enough volume of these parts, the purchase of an Electron Beam Welding system would make sense for your company. However, another feasible solution for smaller scale production levels is to sub-contract out the EB Welding to an experienced job shop. |
