Nd:Yag- and CoD2-Lasers: Welding Applications for Aluminum Lightweight Structures
Published July 02, 1997 by Associazione Tecnica Dell'Automobile in Italy
In mass production of car bodies, laser beam welding offers different well known advantages as for example high feed rate, high weld quality and minimized heat affected zone. It is therefore applied to different production purposes as e.g. for the welding of tailored blanks. Concerning tailored blanks, this paper shows that tensile strength and formability of laser welded aluminum alloys attain values up to those of the base material. It is also reported about the influences of joint geometries on quality and tensile strength of sheet-extrusion joints on aluminum alloys.
