Disclosed is a robot welding assembly mechanism and an application in annular welding seam detection and postweld heat treatment. The robot welding assembly mechanism comprises a rotatable column. A plurality of transverse clamping portions are disposed at intervals on the column. A height-adjustable first V-shaped support portion is disposed at a periphery of the column. The first V-shaped support portion is mounted on a radial track. An annular track is disposed on an outer side of the radial track. A plurality of height-adjustable second V-shaped support portions are disposed on the annular track. The first V-shaped support portion and the second V-shaped support portions are capable of supporting a non-welded portion of the welded workpiece. A first driving mechanism of the rotation base, a second driving mechanism of the transverse clamping portions, and a third driving mechanism of each of the second V-shaped support portions are connected with a control system.
