Stress reducing method in structures formed by electron beam welding of high melting materials guides electron beam in wavy path to form linear and circular seams in welding plane

摘要

When forming linear and circular welding seams, electron beam is guided in wavy path in continuously changing shape in welding plane and direction.Thus wave-shaped welding seams aer produced and shrinkage considerably reduced. Preferably, overlapping, buff, border and pin seams can be formed in wavy shape in tungsten, molybdenum and similar metals.
