Abstract: A welding method includes sandwiching a first base material and a second base material between a first block and a second block, the first and second base materials being made of a light-transmitting resin, and welding the first and second base materials to each other by making a laser beam enter the second base material through a front surface of the second base material toward the first block from outside an outline of the second block at an acute entry angle with respect to the front surface of the second base material and by focusing the laser beam on the first and second base materials between the first and second blocks.

Abstract: A light source emits a laser beam to the object through an output end. An optical system is placed between the output end and the object. The optical system adjusts the energy of the laser beam emitted, through the output end, onto a unit area for a unit time. The energy of the beam spot on the object enables cutting or bending of the object. The optical system serves to adjust the energy of the laser beam irradiated to the object. The energy of the laser beam instantly changes as compared with the case where the energy of the laser beam is adjusted based on a driving voltage applied to a laser oscillator. The object is thus processed by using the laser beam with high accuracy.

Abstract: A laser processing method includes the steps of: preparing a long metal object to be irradiated; and irradiating the object with a laser beam at a certain portion in a longitudinal direction of the object. The irradiation is performed along a width direction of the object for both a first half path from one end to the other end of the object in the width direction and a return path from the other end to the one end so that the object can be bent.

Abstract: A method of processing a film substrate includes removing a portion of the film substrate; and fusing a part of the film substrate around the removed portion to seal scraps of the film substrate, which are generated when removing the portion of the film substrate, in the fused part of the film substrate.
