ABSTRACT:
In this laser beam machine1, while a pressing portion9of an optical guide member6presses a lid13against a body12of a container, the optical guide member6annularly guides a laser beam propagated through an optical fiber4and outputs it from the pressing portion9. Thereby, an annular processing region of the body12and the lid13is entirely irradiated with the laser beam at one time and the lid13can be joined to the body12, whereby improving the working efficiency. Such improvement in working efficiency shortens the processing time and improves the production yield. Furthermore, this laser beam machine1does not need to be separately provided with a rotating mechanism for laser beam scanning and a pressurizing mechanism for the body12and the lid13, so that construction of the machine can be significantly simplified.
