Copper is typically the most challenging material to laser weld, welding it to a less expensive dissimilar material such as steel is doubly challenging. This work was done to demonstrate the capability of the fiber laser in this novel material combination. Due to the challenges of welding copper to stainless steel, it is not a widely used application; however some solar panels show examples of these welds. A series of spot welds were made to weld 0.1 mm thick Copper to 0.15 mm thick type, 304, Stainless Steel. A series of copper spot welds onto thin stainless steel sheet were made successfully. The high power density obtained by using a 50 mm focal length lens (normally a cutting lens) produces high quality spot welds. Although much academic work has been carried out on welding dissimilar metals, this process is not widely used in industry. In this case, the appearance of the copper spot weld is most unusual.
