Title:
APPARATUS AND METHOD FOR FORMING A TUBE HAVING AN ARTICLE ATTACHED THERETO
Document Type and Number:
WIPO Patent Application WO2002049784
Kind Code:
A3
Abstract:
In the present invention, at least one tubular blank (A) and at least one article such as a metal stamping (T), to be attached to a hydroformed part, are loaded into a die. The tube is hydroformed using typical methods. The article is positioned in the die such that, when the tube is hydroformed, the final hydroformed tube contacts the article at least at a point. Attachment means, such as a laser welder, are provided with access to the contact point between the article and the hydroformed tube so that a tack weld or other attachment can be made between the article and the hydroformed tube while still in the closed die. The hydroformed tube and attached article are then removed as a joint assembly from the die.
