METHOD OF LASER WELDING OF THIN CONDUCTORS Russian patent published in 2001 - IPC

FIELD: electronic, instrumentation and mechanical engineering. SUBSTANCE: conductors to be welded are shifted in equipment to touch with cylindrical surfaces. Cylindrical surfaces in contact are compressed radially and are subjected to plastic deformation. Profile of weld butt joint is formed being limited by lines of two intersecting semicircles and chord connecting points of intersection of semicircles. Size of chord 1 is (0.2-0.3) D where D is diameter of conductor. Checking of mechanical properties of welded joint shows strength of connection equal to 80% of strength of base material. EFFECT: enlarged operating capabilities and improved quality of weld joints. 1 dwg
