VEHICLE WITH WELDED BUS BAR CONNECTIONS

In a high voltage vehicle electronics system, electronic components having tabs are welded to a bus bar using pulsed laser welding. Each tab is welded to the bus bar with an array of spot welds. Each spot weld includes an inner region formed by laser welding in a keyhole mode and an outer region formed by laser welding in a conduction mode. The energy density applied to the inner region is between ten and twenty times the energy density applied to the outer region.
