Abstract
Two workpieces 30, 40 are joined by means of ultrasound. First, a workpiece 30 with at least one energy direction sensor 31 and a second workpiece 40 are provided. The workpieces are brought into contact with each other in such a way that the energy direction sensor 31 comes into contact with a first surface 41 of the second workpiece 40. Ultrasonic vibrations are then introduced into one of the workpieces 40 via a working surface 11 of a sonotrode 10. A sonotrode 10 is used, which has a contour with contact lines 12 on the working surface 11. The sonotrode 10 is positioned with respect to the first workpiece 30 in such a way that the contact lines 12 run transversely to the energy direction generator 31.
Claims11
A composite article having a first and a second workpiece,
- wherein the first and second workpieces are joined to one another by means of ultrasonic welding, and wherein the first workpiece has an energy direction generator on a side that faces the second workpiece, wherein the article has, on the second workpiece, in a region along the energy direction generator, acoustic introduction impressions which are spaced apart from each other and separated from each other by welding lines and which extend transversely to the energy direction generator.
A method for joining workpieces of different material,
- wherein a first workpiece has a first degree of crystallization at least in the region of an interface facing the second workpiece, a second workpiece has a second degree of crystallization at least in the region of an interface facing the first workpiece, which degree of crystallization is different from the first degree of crystallization,
- wherein at least one of the workpieces is subjected to torsional vibrations at a sound introduction surface and the workpieces are thereby bonded to one another.
A composite article comprising a first and a second workpiece,
- wherein a first workpiece has a first degree of crystallization at least in the region of an interface facing the second workpiece, a second workpiece has a second degree of crystallization at least in the region of an interface facing the first workpiece, which degree of crystallization is different from the first degree of crystallization,
- wherein the workpieces are joined to one another by a welded joint between the interfaces produced by means of torsional ultrasonic vibrations.
