| 摘要 |
The invention relates to an orbital friction welding method and a friction welding device, for welding workpieces (16, 18) by means of friction welding units, wherein the workpieces (16, 18) are pressed against each other in the contact plane (F) during the application of the oscillation energy. To this effect, n>1 friction welding heads [I, II, III, IV or I', II', III', IV' or I'', II'', III'', IV''] are mounted, in a stationary manner, at least on one side of the contact plane (F) in an orbital plane, in the area of the workpieces (16, 18), 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. |
