| "I WANT TO DO AN EB WELD WITH ZERO SPATTER. IS IT POSSIBLE? HOW CAN YOU MINIMIZE SPATTER? THE MATERIAL IS INCONEL 718." |

Absolutely. Electron Beam Welding with zero spatter is entirely possible. Especially with this particular Inconel 718 material, you should be able to develop a weld without having any spatter issues. Weld spatter is typically caused by cleanliness reasons due to contamination of the part- oils, foreign object debris (FOD) left over from prior machining processes, etc. Outgassing can also occur as a result of impurities in the parent material that are ejected (or sometimes trapped) from the weld joint because they have a different melting temperature than the surrounding base metal you are trying to join. A secondary cause of this issue could be the welding parameters you are using, but we strongly recommend that you rule out all of the above reasons as a preliminary measure. |
