Principle<br />
Heating the joining<br />
partners using a heating<br />
element or hot gas,<br />
joining under pressure<br />
Heating a joining zone<br />
(with a specific geometry)<br />
by ultrasound vibration<br />
Welding time 20 to 40 s 0.1 to 2 s 0.2 to 10 s<br />
Benefits<br />
High strength,<br />
low cost<br />
Minimal cycle times,<br />
easy process automation<br />
