Abstract (en)

[origin: WO2022043107A1] The present invention relates to a method for connecting a first joining surface of a first workpiece to a second joining surface of a second workpiece, said method having the steps of: 1) bringing the first and the second joining surface into contact with each other, 2) bringing a first tool part into contact with the first workpiece, and introducing energy into the first workpiece via the first tool part. In order to specify a method which can also weld materials having a low thermoplastic component or even materials without a thermoplastic component, without having to resort to adhesives, it is proposed in accordance with the invention that, before step 1), a step of: A) applying particles formed from thermoplastic material to the first and/or second joining surface is performed.
