Zusammenfassung:	The invention discloses a self-positioning welding clamp for a turbine device assembly. The self-positioning welding clamp comprises a first positioning assembly, a positioning shaft and a second positioning assembly. The first positioning component is provided with a first elastic positioning structure which can radially close and clamp the outer ring surface of the first component under the action of external force to enable the first component and the first component to be coaxial; the second positioning assembly is provided with a second elastic positioning structure for clamping the third component to enable the third component and the second component to be coaxial; the axis position of the first elastic positioning structure is provided with a shaft positioning structure matched with the positioning shaft in a radial positioning mode, and the axis position of the second elastic positioning structure is provided with a shaft mounting structure used for positioning and fixing the positioning shaft.
