Friction welding resist

Polytetrafluoroethylene (PTFE, or Teflon) is reported to resist friction welding to other polymers even at high speeds and pressures [24]. PTFE has a much lower coefficient of friction and relatively higher softening point among the polymers. To reach the necessary conditions to weld it, sliding speed and pressure should be increased by a factor of 50 and 20 in comparison with high-density polyethylene [19]. [Pg.606]

Receivers are commonly made of steel tuhe with welded dished ends, and are located horizontally. Small receivers may he vertical, for convenience of location. The liquid drain pipe from the condenser to the receiver should he amply sized, and any horizontal runs sloped to promote easy drainage. Shut-off valves in this line should not he in a horizontal outlet from the condenser, since their slight frictional resistance will cause liquid hack-up in the condenser. Oudet pipes from the receiver may he from the bottom or, by means of an internal standpipe, may leave at the top. A valve is invariably fitted at this point. [Pg.80]

Cylindrical pin hutt joint tools were used in the hrst friction stir lap welding (FSLW) attempts. These tools produced uplift adjacent to the friction stir zone and thinning of the upper sheet (Fig. 2.20). Interface uplift is produced by verhcal flow adjacent to the pin, which sharply moves the joint interface upward (typically on the advancing side of the tool). The angle of uplift can reach 90° and greatly reduces the fahgue resistance of the joint. Thinning of the... [Pg.20]
