PURPOSE:To stick evenly irrespective of size of an adhesive area, by a method wherein two bodies composed of thermoplastic resin which are weldable to each other are welded with pressure, pressure welding faces are melted through frictional heat by giving relative reciprocation running parallel with the pressure welding face between both the bodies and the relative reciprocation is suspended. CONSTITUTION:Plane bodies 1, 2 composed of the same thermoplastic resin are held respectively on the top of a stationary holding table 3 and the undersurface of a movement holding table 4 through suction and pressure welding of the plane body 2 to the plane body 1 is performed with appropriate pressure by lowering the movement holding table 4. Then when the movement holding table 4 is reciprocated in parallel with the pressure welding face by a reciprocation device, it becomes that the pressure welding faces of the plane bodies 1, 2 are heated through mutual friction and melting together. At a point of time when the whole surface of the pressure welding faces are melted, the reciprocation of the movement holding table 4 is suspended and a joined body obtained by welding the plane bodies at the pressure welding faces is taken out. With this construction, the title bodies can be welded together uniformly and strongly irrespective of size of an adhesive area and without restriction of a kind of the thermoplastic resin or a form of the body of the thermoplastic resin. |
