According to the Intergovernmental Panel on Climate Change (IPCC), a worldwide reduction of CO2-emissions is indispensable to avoid global warming. Besides the automotive sector, lightweight construction is also of high interest for the maritime industry in order to minimize CO2-emissions. Using aluminum, the weight of ships can be reduced, ensuring lower fuel consumption. Therefore, hybrid joints...
In der industriellen Fertigung von Schiffen, Pipelines und Mobilkränen werden hochfeste Feinkornbaustähle, die durch Vorteile bezüglich Schweißeignung und mechanisch‐technologischer Eigenschaften gekennzeichnet sind, im Dickblechbereich eingesetzt. Konventionell werden Feinkornbaustähle durch mehrlagige Lichtbogenschweißverfahren mit relativ geringer Schweißgeschwindigkeit gefügt. Dabei sind sowohl...
The industrial useof GMA-laser hybrid welding has increased in the last 10 years, due to the brilliant quality of the laser beam radiation, and higher laser output powers. GMA-laser hybrid welding processes operate in a common molten pool. The combination of the laser beam and the arc results in improved welding speed, penetration depth, heat affected zone and gap bridgeability.Single-layer, GMA-laser...
