ABSTRACT:
In a method of welding with a beam of charged particles, outside of a mobile vacuum chamber a gap between two workpiece parts is sealed by an elongated metal foil strip, two marginal zones of which being sealingly cemented to surface portions of said workpiece parts, said marginal portions being sufficiently spaced from the gap to avoid excessive heating of the adhesive during welding a seam along said gap. The preferred material for the foil strip is copper or austenitic steel.
