Deep spot welds require the formation of a capillary and this again defines the processing time for each weld which is of particular interest for achieving high productivity. The capillary formation and the depth progress are influenced by the laser beam parameters. Spot welding with a laser power of up to 16 kW, a wavelength of 1030 nm and, beam diameters of 200 μm and 600 μm were investigated. High-speed X-ray imaging with a temporal resolution of 0.5 ms during the welding process was used to analyze the capillary depth progress. With the maximum power of 16 kW, a capillary depth of 4 mm was achieved in copper within 5 ms.
