Manufacturing straight bead welded wire involves forming metal strip into slotted tube, electron beam welding along weld joint formed by slot, switching beam between slotted tubes

摘要

The method involves forming a metal strip into a slotted tube and electron beam welding along the weld joint formed by the slot. The electron beam (ES) is switched between the joint seam of at least two slotted tubes (36) with a defined changeover frequency. The electron beam is changed over transversely wrt. the joint seam at a frequency between 100 kHz and 3.2 MHz. An Independent claim is also included for an arrangement for implementing the method.
