Laser micro spot welding offers temperature resistant high strength contacts without filler material. However, due to varying surface absorption properties of copper, the welding quality shows poor reproducibility. To ...

The development within the offshore wind sector towards more powerful turbines combined with increasing water depth for new wind parks is challenging both the designer as well as the manufacturer of bottom fixed support ...

Due to the enormous potential of weight saving, and the consequential reduction of pollutant emissions, the use of hybrid components made of steel and aluminum alloys is increasing steadily, especially concerning automotive ...

This article contains findings of simulation research on longitudinal induction welding of cladded pipes with use of simultaneous double frequency. Solutions are proposed to reach the required temperature distribution at ...

In order to produce three-dimensional components from metals, a wide variety of processes exist. Laser processes combined with metal powders are frequently used and developed. Restrictive factors are the machine-related ...

The back end process of passivated emitter and rear cells (PERC) consists of at least one laser process and three screen-printing steps followed by the stringing and tabbing of the cells. To reduce the number of steps we ...

This publication presents the advantages of NVEB technology as an universal tool for material processing based on our investigations on welding and cutting of high-strength S960QL, S1100 and S1300 steels. In this work, the ...
