Abstract
A method for manufacturing a turbocharger () with variable turbine geometry (VTG), having a turbine housing () with a feed duct () for exhaust gases; a turbine rotor () which is rotatably mounted in the turbine housing (); and a guide grate () which surrounds the turbine rotor () radially at the outside, which has a blade bearing ring (), which has a multiplicity of guide blades () which have in each case one blade shaft () mounted in the blade bearing ring (), which has an adjusting ring () operatively connected to the guide blades () via associated blade levers () fastened to the blade shafts () at one of the ends thereof, each blade lever () having at the other end a lever head () which can be placed in engagement with an associated engagement recess () of the adjusting ring (), and which has a stop () at least for setting the minimum throughflow through the nozzle cross sections formed by the guide blades (). The stop () is formed as a setting pin which is fastened by means of an automated butt welding process, the position of the setting pin being determined from a previously carried out throughflow measurement with similar guide grates.
