An improved wastegate valve for turbochargers having bifurcated exhaust gas inlets includes a first bypass port communicating with a first portion of the exhaust inlet, a first poppet which engages and seals a seat surrounding the first port, a second bypass port communicating with a second portion of an exhaust inlet, and a second poppet which engages and seals a seat surrounding the second port. Actuation of the poppets is accomplished by a first substantially tubular shaft supported for rotation about an axis and having a central bore and a second substantially tubular shaft extending through the central bore of the first shaft and supported therein for rotation about the axis. The two shafts are concurrently rotated by a lever arm which is connected to the first shaft, at an opposite end to the radial arm, with a weld bead which extends across the end face of the first shaft, the bore, and a coplanar end of the second shaft.
