Title
(EN) GALVANIZED MULTI-TUBULAR BEAM AND METHOD OF CONTINUOUSLY FORMING THE SAME
(FR) POUTRE GALVANISÉE À TUBES MULTIPLES ET SON PROCÉDÉ DE FORMATION CONTINUE
Abstract
(EN)
A galvanized reinforcement beam is continuously formed by uncoiling a roll of galvanized sheet stock in a generally horizontal plane. Protrusions are formed at an upper surface of the sheet stock, which is then roll formed to form a tubular shape with the protrusions abutting a surface of the sheet stock to form venting gaps. The sheet stock is laser welded at the protrusions to continuously form a weld joint, where zinc oxide gas generated from the welding is permitted to escape an interior of the tubular shape through the venting gaps.
(FR)
Cette invention concerne une poutre de renforcement galvanisée, formée en continu par déroulement d'un rouleau de feuillard galvanisé dans un plan généralement horizontal. Des saillies sont formées sur une surface supérieure du feuillard, qui est ensuite profilé pour obtenir une forme tubulaire, les saillies venant en butée contre une surface du feuillard pour former des espaces d'aération. Le feuillard est soudé au laser au niveau des saillies pour former en continu un joint de soudure, le gaz d'oxyde de zinc généré par le soudage étant autorisé à s'échapper d'un intérieur de la forme tubulaire à travers les espaces d'aération.
