The invention discloses a welding assembly for a shock absorber lug. The welding assembly comprises a base and a vertical column arranged on the base, wherein at least two V-shaped blocks are arranged on the base; a cross beam is arranged on the vertical column; a cylinder A and a cylinder B which are located above the two V-shaped blocks are arranged on the cross beam; a piston rod of the cylinder A is downward; a compressing block A is arranged at the bottom of the cylinder A; a piston rod of the cylinder B is downward; a compressing block B which is used for positioning a lug is arranged at the bottom of the cylinder B. The welding assembly for a shock absorber lug has the advantages of facilitating clamping of a welded component, being simple to operate, reducing labor intensity, and ensuring high accuracy in aligning the welding position, short aligning time and high consistency and stability of welded products.
