Abstract The present invention relates to a weld joint for metal pipes. The object is to provide a weld joint which is easy to make and which has a clean surface inside the pipes. The ends of the pipes to be joined are flared and between the inner conical surfaces of the flared pipe ends is arranged a cylindrical metal sealing ring under axial compression, the edges of the ring being elasti- cally bent inwards by said inner conical surfaces of the flared pipe ends. The sealing ring is preferably provi- ded with a circumferential flange projecting out between the pipe ends, for facilitating correct positioning of the sealing ring. (Figure 1)
