|"HOW CAN FILLER MATERIAL BE ADDED TO THE EB WELDING PROCESS IF REQUIRED? IS THERE ANY SPECIAL ARRANGEMENT FOR THAT? PLEASE EXPLAIN."|
Filler material can be added to the electron beam welding process in a few different ways. The most common way to introduce filler material is to add shim material in the weld joint. As the joint is consumed in that location, there will be additional material flowing into the weld.
A wire feeder can also be used. (See image below.) The wire feeder is a multi-axis, CNC controlled device which properly positions the wire in relation to the beam and workpiece. Depending on the particulars of your EB welder, these units are available as add-ons to existing systems.
