  1. 1. Dynamik und Stabilität der Dampfkapillare beim Laserstrahltiefschweißen

    Författare :Jörg Volpp; Germany Universität Bremen; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser deep penetration welding; keyhole dynamics; pore and spatter formation mechanisms;

    Sammanfattning : The keyhole which is typical for laser deep penetration welding is responsible for the highly dynamic process behavior, which results in unwanted pore and spatter formation. This work aims to better understand the dynamic keyhole properties and occurrence of process defects. LÄS MER
