FIELD: technological processes.
SUBSTANCE: invention relates to an overlap welding method, a lap weld joint, a method for manufacturing a lap welded joint and a vehicle part that includes a lap joint. Method of overlap welding involves stacking a plurality of steel sheets on one another and igniting the laser to form substantially circular laser weld (1). In the welding process, the laser is moved in a straight line through the outer edge of substantially circular laser weld (1) so as to form reinforced portion (8) in steel sheets.
EFFECT: suppression of the occurrence of cracks arising from the formation of a softened part of the zone of thermal influence.
