1. A method for manufacturing a turbocharger (1) with variable turbine geometry (VTG), the method comprising:

  • manufacturing the turbocharger comprising;

    a turbine housing (2) with a feed duct (9) for exhaust gases;

    a turbine rotor (4) rotatably mounted in the turbine housing (2); and

    a guide grate (18) which radially surrounds the turbine rotor (4), the guide grate comprising;

    a blade bearing ring (6), a multiplicity of guide blades (7) each having a blade shaft (8) mounted in the blade bearing ring (6), an adjusting ring (5) operatively connected to the guide blades (7) via associated blade levers (20) fastened to the blade shafts (8) at one of the ends thereof, each blade lever (20) having at the other end a lever head (23) which can be placed in engagement with an associated engagement recess (24) of the adjusting ring (5), and a stop (25) for setting a minimum throughflow through nozzle cross sections formed by the guide blades (7),wherein the stop (25) is a setting pin which is fastened by means of an automated butt welding process, a position of the setting pin being determined from iterative throughflow measurements.
