Abstract
The invention relates to an orbital friction welding method and a friction welding device for welding workpieces by means of friction welding units, wherein the workpieces are pressed against each other in the contact plane during the application of the oscillation energy. To this effect, n>1 friction welding heads are mounted, in a stationary manner, at least on one side of the contact plane in an orbital plane, in the area of the workpieces so that the n>1 friction welding heads, respectively facing one side, are oscillated with the same friction frequency, the same amplitude and the same preset phase position.
Claims21
An orbital friction welding method for the welding of workpieces, wherein the workpieces, during the introduction of the vibratory energy, are pressed together at a joining plane,
- characterized in that
- at least one side of the joining plane, more than one (n>1) friction welding heads are so mounted to at least one friction disk in an orbital plane in the area of the workpiece that vibration heads of the friction welding heads are stationarily attached to the friction disk, and
- the more than one (n>1) friction welding heads, which are proximal to one side, respectively, are set into vibration at the same friction frequency and the same amplitude as well as with an equal, predetermined phase position.
