FIELD: metallurgy.
SUBSTANCE: connection is obtained by laser welding. Metal sheets are placed overlapping each other. Welding by laser beam is performed in direction of application. Weld seam with width equal to 0.6t1/3+0.14 (mm) is obtained or more, where t is total thickness of welded superimposed metal sheets, mm. As a result, weld joint has improved shear strength at tension, wherein it is obtained without increasing welding time and without using an expensive remote laser head.
EFFECT: invention relates to a weld joint of metal sheets and a method for production thereof.
