This limits the holding force, which of course must be taken into account when determining the parameters for friction welding.

For this purpose, the friction welding units 30 are correspondingly displaceably arranged on a machine bed 80, which is indicated by double arrows attached to the sides of the friction welding units.
  • An explanation of the device for displacing the individual friction welding units is not necessary, because conventional measures are available in a variety of ways.
  • FIG. 10 shows the multi-head friction welding device shown in FIG.
  • the measures of the invention provide significant advantages, since the cycle time can be considerably reduced compared to the mirror welding and the post-processing of the welded areas to eliminate the welding drives can take place immediately after the joining, since the weld seam cools down very quickly.
