FIELD: process engineering.
SUBSTANCE: invention relates to welding and may be used in point welding of lap joints not requiring tightness. Welded lap joint consists of top and bottom elements connected by common weld point. Said weld point has a through flowed bore made at point center through both said elements. Made point with bore features toroidal shape that increases cross-section area at lap interface between bonded elements to up destructing force at shear load.
EFFECT: higher strength of weld joint, simple quality control.
