The method for welding adjacent faces of injection or extrusion mould products, is composed of combining the moulded products with a jig having expansion space, heating the jig at 320-380 deg.C for 3-30 minutes, and welding the adjacent faces by the heat and expansion pressure of the jig. The expanding space of the jig is 20-70 % of fluoride resin expanding space in the expanding ratio.
