Abstract:
1. A system for joining a filler material to a substrate material, the system comprising: a crucible having a melting chamber for holding the filler material, the crucible comprising an outlet system including a nozzle fluidly connected to the melting chamber, the nozzle having an entrance segment having a first length and fluidly connected to an opening in the crucible, a tapered segment following the entrance segment and having a second length and tapering radially inward relative to a central longitudinal axis of the crucible, and an outlet segment having a third length following the tapered segment; a heating element operatively connected to the crucible for heating the filler material within the melting chamber of the crucible, the heating element being configured to melt the filler material within the melting chamber such that the filler material is molten; and a flow control mechanism operatively connected to the crucible for controlling flow of the filler material through the outlet system of the melting chamber, the flow control mechanism being configured to apply a pressure differential across the outlet system of the crucible, wherein the pressure differential holds the filler material within the melting chamber.
