Title (EN) METHOD OF LASER BEAM WELDING OF ZINC-COATED STEEL SHEET
(FR) PROCEDE DE SOUDAGE PAR FAISCEAU LASER DE TOLES D'ACIER REVETUES DE ZINC
Abstract: front page image
(EN)A pair of coated components are laser welded to one another by initially forming protuberances on one of the components. The protuberances maintain juxtaposed surfaces separated and the components are then laser welded to one another. The separation of the surfaces vents vapor generated by the coating.
(FR)Deux éléments revêtus sont soudés au laser l'un à l'autre par formation initiale de protubérances sur un des éléments. Les protubérances maintiennent les surfaces juxtaposées séparées et les éléments sont ensuite soudés au laser l'un à l'autre. La séparation des surfaces permet la ventilation de la vapeur générée par le revêtement.
