A machining apparatus includes a light source () for generating light energy, an optical system () for guiding the generated light energy to a joint position of a workpiece, a table () on which the workpiece is mounted, and a heating device () provided at the table for heating the workpiece. The machining apparatus, a machining method and production equipment using the machining apparatus allow the workpiece to be locally heated fast, which is applicable to soldering or the like.

Light energy processing device and method

An optical processing apparatus has high reliability and stable welding quality. In the processing apparatus, a semiconductor laser and an optical system are disposed to a flow path of processing gas. The gas protects the semiconductor laser and the optical system from moisture and dust while cooling them. In addition, the apparatus also leads the processing gas to flow through a holder of the optical system to increase cooling effect for the optical system and to improve an optical accuracy. The apparatus guides the processing gas along a surface of a cover glass inside a nozzle ejecting the processing gas to a workpiece, to prevent the surface of the cover glass from being damaged and stained. The processing gas is ejected in a direction coaxial with a direction of output light, so as to shield an area being processed.
