[en] This invention provides a process and device for simultaneous laser welding; after using the moving lower die (5) and the fixing upper die (6) to make the base (14) and the lens (13) attached, by using the light pipe (12) to make the laser, which is emitted from the laser source (11), emit through the lens (13) to a welding region of the base (14) after being processed, to operate rapid and average heating to the welding region; meanwhile, using the welding cylinder (3) to press the base (14) and the lens (13) together, to make base (14) and the lens (13) pressed and welded together in molten state, and when welding, it does not generate powder or other defects, and, at the same time, it can make the height H and the width w of the generated waste selvage between [0, 0.4] mm, which can improve the performance of welding object more efficiently.
