ABSTRACT:
A deep penetration weld join is produced in an energy beam welding method where the energy beam, as for example, an electron beam, is directed into the join to produce a welding zone containing molten material, and moved along the join relative to the parts of the work. Additional material is introduced into the welding zone to fill a gap and/or to influence the metallurgical composition of the weld zone. By introducing the material into the melt at an acute angle to the beam axis and at a point spaced alongside the beam axis, the additive material penetrates deeply into the molten material. The additive material may be preheated prior to its introduction to the welding zone.
