  • the at least one welding bag may advantageously be present on one or both parts. In addition, it can also come through the interaction of both parts to the emergence of a favorable welding bag.
  • a second part has a first projection on which the first part abuts during welding, because this creates a defined welding point, which creates a tight connection between the parts.

Abstract

Relier deux parties, formant un dispositif, selon la technique actuelle est coûteux et nécessite des éléments supplémentaires pour l'obtention d'une liaison étanche. Selon la présente invention, un dispositif (1), comprenant deux parties (3, 6), présente des cavités de soudure (9) à l'intérieur desquelles de la matière peut pénétrer lors du processus de soudure, de manière à former une liaison.
