Welding tool for air suspension thrust bearing

The invention discloses a welding tool for an air suspension thrust bearing. The welding tool comprises a back plate bracket used for fixing a thrust bearing back plate and a foil limiting plate detachably connected with the back plate bracket and installed above the thrust bearing back plate. The foil limiting plate comprises a horizontal limiting block, the horizontal limiting block is circular, the diameter of the horizontal limiting block is smaller than that of the thrust bearing back plate, after the horizontal limiting block and the back plate bracket are fixedly installed, the area, not covered by the horizontal limiting block, of the thrust bearing back plate forms a foil welding area, and the periphery of the horizontal limiting block extends outwards at equal intervals to be provided with the foil limiting blocks. The back plate of the thrust bearing is positioned and fixed through the back plate bracket, and the bump foil and the flat foil are positioned and welded through the foil limiting plate,
