LÖT 2022
13th International Conference on Brazing, High Temperature Brazing and Diffusion Bonding
https://www.dvs-ev.de/call4papers/index.cfm?vid=113Vom 21. bis 23. Juni 2022 findet in Aachen die 13. Internationale Konferenz für Hartlöten, Hochtemperaturlöten und Diffusionskleben statt. Diese Konferenz ist eine der weltweit führenden Veranstaltungen auf diesem Gebiet. Sie bringt Wissenschaftler, Ingenieure und technisches Personal aus der ganzen Welt zusammen, die sich mit der Forschung, Entwicklung und Anwendung der Fügetechnik beschäftigen.
Die Welt hat sich seit der letzten Konferenz dramatisch verändert. Selbst in Zeiten einer globalen Pandemie schreitet die technische Entwicklung voran. In den Unternehmen ist die Digitalisierung vorangeschritten, die Geschäftsprozesse wurden optimiert und die Kundenbeziehungen gestärkt. Hartlöten, Hochtemperaturlöten und Diffusionskleben sind komplexe Technologien, die kontinuierlich weiterentwickelt werden müssen. Sie beruhen auf aktuellen Forschungsergebnissen, geltenden Normen und Richtlinien sowie angepassten Schulungsmaßnahmen.
Insbesondere die Löttechnik bietet den Herstellern eine Vielzahl interessanter und wirtschaftlicher Lösungen zum Verbinden von Werkstoffen und Produkten. Auch für die Anwendung dieser Fügeverfahren ist ein besonderer Wissensstand erforderlich, der sich aus dem anwendungsorientierten Informationsaustausch zwischen Praxis und Wissenschaft ergibt Die Ziele der Tagung sind
- Präsentation von technischen Lösungen für moderne Anwendungen
- Transfer von wissenschaftlichen Ergebnissen in die betriebliche Praxis
- Information über die neuesten Trends und technologischen Entwicklungen
- Vorstellung von Anwendungsfeldern für neue Materialien
- Aufbau oder Intensivierung von Kontakten zwischen Anwendern und Forschern
