  • INTERFACE SUSPENSION FOR ALLOY BASED LASER WELDING
    Publication number: 20090283505
    Abstract: An interface suspension facilitates laser welding of a first metal having a first zinc coating to a second metal having a second zinc coating. The interface suspension includes a petrolatum base and a plurality of spherules suspended in the petrolatum base. The interface suspension melts when the zinc coated metals are welded to allow the plurality of spherules to maintain a gap between the first and second metals. This allows vapors of zinc to escape through the gap during the weld process to maintain the integrity of a resulting weld.
