Abstract

Abstract Translated from German Die Erfindung bezieht sich auf einen Brenner zum Mikroplasmaschweißen, der der hohen Dauerbelastung bei der Serienfertigung Stand zu halten in der Lage ist. Bei dem Brenner gemäß der Erfindung weist der Plasmakanal (10) der Plasmadüse an der Eintrittsstelle des Plasmas einen gegen die Spitze der Elektrode (12) gerichteten erhöhten Ringrand (13) auf. Ferner ist die Elektrode (12) zur Ermöglichung eines erhöhten Wärmeabtransportes entsprechend stark bemessen und mit einer eigenen Kühlung (17, 20) versehen. Schleißlich besitzt der Brenner eine diffusionsdichte Plasmagaszuleitung (29). The invention relates to a torch for micro plasma welding, which is able to withstand the high continuous load in series production. In the burner according to the invention, the plasma channel (10) of the plasma nozzle has an elevated ring edge (13) directed towards the tip of the electrode (12) at the entry point of the plasma. Furthermore, the electrode (12) is dimensioned correspondingly strong to enable increased heat removal and is provided with its own cooling (17, 20). The burner finally has a diffusion-tight plasma gas feed line (29).
