Le partenaire<\/h5>\n\n\n\n

Fond\u00e9 en 1986, l\u2019Institut f\u00fcr Strahlwerkzeuge (IFSW)<\/a> de l\u2019Universit\u00e9 de Stuttgart est connu pour \u00eatre l\u2019un des principaux centres de recherche sur les proc\u00e9d\u00e9s laser au monde. Il \u00e9tudie tous les aspects, des sources laser \u00e0 leurs applications, en passant par les investigations fondamentales et le transfert de technologie industrielle. Actuellement, une part de son activit\u00e9 est consacr\u00e9e l\u2019utilisation de la mise en forme du faisceau.<\/p>\n\n\n\n

L\u2019application<\/h5>\n\n\n\n

L\u2019un des grands d\u00e9fis de l\u2019e-mobilit\u00e9 est le<\/strong> soudage du cuivre<\/strong>. En effet, un grand nombre de composants n\u00e9cessaires au fonctionnement des batteries sont en cuivre et doivent \u00eatre soud\u00e9s entre eux. Par exemple, les busbars<\/strong> sont des pi\u00e8ces de cuivre qui doivent \u00eatre soud\u00e9es afin d\u2019assurer le passage de l\u2019\u00e9lectricit\u00e9<\/strong> d\u2019un composant \u00e0 l\u2019autre (typiquement batterie, moteur, etc.)<\/p>\n\n\n\n

La probl\u00e9matique<\/h5>\n\n\n\n

L\u2019IFSW souhaite une technologie de mise en forme sur mesure permettant une qualit\u00e9 de soudure du cuivre optimale, c\u2019est-\u00e0-dire sans pore ni projections<\/strong>. Il s\u2019agit aussi de trouver une solution industrielle, robuste, et donc avec une fen\u00eatre de processus (gamme vitesse\/puissance) la plus large possible.<\/p>\n\n\n\n

La solution CANUNDA-HP<\/h5>\n\n\n\n

La t\u00eate CANUNDA-HP Custom<\/strong> d\u00e9livre un faisceau compos\u00e9 d\u2019un spot intense entour\u00e9 d\u2019un anneau<\/strong>, id\u00e9al pour le soudage du cuivre. De conception toute r\u00e9flective<\/strong>, gr\u00e2ce \u00e0 la technologie MPLC, avec un refroidissement optimal des optiques, elle permet de g\u00e9rer les hautes puissances<\/strong>.<\/p>\n\n\n\n

Int\u00e9gration industrielle de la t\u00eate laser CANUNDA-HP Custom<\/h5>\n\n\n\n

La t\u00eate CANUNDA-HP sur-mesure a \u00e9t\u00e9 utilis\u00e9e dans les locaux de l\u2019IFSW pour la r\u00e9alisation de soudures sur des \u00e9chantillons de cuivre Cu ETP<\/strong> de dimension 100 mm x 30 mm x 4 mm, avec un apport de gaz de protection Argon. Une matrice d\u2019essais 3 x 7 (trois valeurs de puissance et sept valeurs de vitesse robot) est analys\u00e9e par rayon-X en live afin de d\u00e9terminer la longueur du capillaire et de visualiser les formations de pores et les projections. Pour cela on place un tube \u00e0 rayons X devant et cam\u00e9ra derri\u00e8re l\u2019\u00e9chantillon.<\/p>\n\n\n\n

La t\u00eate laser CANUNDA-HP sur-mesure est configur\u00e9e pour d\u00e9livrer un anneau de de 400 \u00b5m<\/strong> de diam\u00e8tre et un spot de 100 \u00b5m de diam\u00e8tre<\/strong> (70% de l\u2019\u00e9nergie dans l\u2019anneau, 30% dans le spot central).<\/p>\n\n\n\n

\u00abNous \u00e9tudions \u00e0 l\u2019IFSW diff\u00e9rentes technologies laser permettant d\u2019am\u00e9liorer les soudures de cuivre, dont l\u2019enjeu pour la mobilit\u00e9 \u00e9lectrique est important. Gr\u00e2ce \u00e0 notre analyse en cours de soudure aux rayons X de l\u2019\u00e9chantillon, la solution Cailabs a d\u00e9montr\u00e9 une stabilit\u00e9 de cordon et une qualit\u00e9 de soudure compatibles compatibles aux besoins de l\u2019industrie. \u00bb.<\/em><\/p>\n\n\n\n
