中文摘要	Focusing on thin sheet high-speed laser welding, this study used 0.19- and 0.21-mm-thick, chromium-plated sheet as the research object and studied influences of the elongated spot length on the thin sheet laser welding speed when adopting butt joint welding by different focus elongated spot patterns from both theoretical and experimental points of view. It showed from the test result that compared with the normal spot pattern, the welding speed was increased by 41.6% for 0.19-mm-thick, chromium-plated sheet when the laser power was 1.5 kW and elongated spot length was 4.3 mm, while the welding speed was increased by 30.5% for 0.21-mm-thick, chromium-plated sheet upon elongated spot butt joint welding. Furthermore, compared with the normal spot pattern, sagging of the weld joint end face resulted by the elongated spot would be greatly reduced. Thus, it was clear that the welding speed for the thin sheet could be increased with the weld joint quality improved when the suitable elongated spot pattern was adopted.
