| Abstract Scope |
Lightweighting of an all-steel engine cradle was accomplished by converting to a multi-material structure containing stamped 5052 grade aluminum in addition to HSLA 340 steel. The components were impact welded together by several vaporizing foil actuator welds made by a hydraulically closing weld head energized by a capacitor bank with a maximum charging energy of 4.2kJ. The welds were tested at the coupon scale and exceeded the requirements under simulated static and cyclic loading conditions. The welded interface was heterogeneous in structure as well as composition with some regions being flat and some being wavy, as is typical in impact welds. Vaporizing foil actuator welding will be presented in terms of the basic process, equipment, consumables and versatility in weldable material combinations and configurations. The particular application of welding up an engine cradle will be discussed from the perspective of material selection, mechanical testing and characterization of the welds. |
