    Abstract: A method and apparatus for positioning and holding a pair of sheet metal blanks to be butt welded into a compound blank for stamping a larger panel with varying thicknesses. A fixture plate is provided with locating corners matching predetermined reference corners of the blank and with mechanisms for pushing the blanks into the locating corners. The first blank is pushed into abutment with stops that are then pivoted out of the way, after the first blank is clamped in place. The second blank is then abutted with the already clamped first blank, and clamped. The loaded fixture is then transported to a weld station, where the pre positioned blanks can be quickly and efficiently laser welded.

    Abstract: A shaft bearing is formed from an aluminum alloy that has approximately 8% Sn, 4% Si, 2% Pb and 1% Cu on a weight percentage basis. The tin has an average particle size less than five microns and the silicon has an average particle size less than 3.5 microns. The alloy is formed into a continuous solid strip by a quench casting operation, wherein molten alloy is fed into an interface between two internally-cooled rolls to freeze the alloy into a solid strip condition in less than one second. The aluminum alloy strip is pressure bonded to a steel backing strip to form a composite strip useful in forming a shaft bearing. During the pressure bonding step the thickness of the aluminum alloy strip is significantly reduced while the thickness of the steel strip remains essentially unchanged.
