Investigation of nickel coated steel tapes welded joints

Abstract

Abstract Nickel-plated steel tapes are primarily developed for battery production. The aim of these developments was to provide all battery cell cases with good contact resistance and high corrosion resistance, thus increasing their durability. When individual battery cells are packaged, the electrical connection is also mostly made with nickel-plated plates. Welding and soldering are the bonding technologies used to make the connections between the plates, but the advantages mentioned above may vary when making these connections. To our knowledge, lasers with diode beam sources are the most efficient and are becoming more and more suitable for a wide range of applications as the technology develops. The aim of our investigations is to investigate the quality of joints made with low power diode lasers with different parameters from a strength and metallographic point of view.
