Abstract: Provided are a machining device and a machining method in which machining of higher precision can be performed with a simple configuration. The machining device has an irradiation head (16) and a controller; and the irradiation head (16) can be divided into a collimate optical system, a laser revolving unit (35), and a light collection optical system (37). The laser revolving unit (35) has a first prism (51), a second prism (52), a first rotation mechanism (53), and a second rotation mechanism (54). The controller controls the rotational speeds and the difference in phase angles of the first prism (51) and the second prism (52), on the basis of at least the relationship between a heat affected layer of a member to be machined and the revolving speed of the laser.

Abstract: A method of impact welding a flyer to a hollow component is provided. The method includes providing the component made of a first material and including a cavity where a weld site is disposed on a first side of the component. An incompressible material is packed against a second side of the component opposite the first side facing the cavity. A flyer made of a second material is positioned onto the weld site. The flyer is then impact welded to the component. The incompressible material prevents the deformation of the component during the impact welding. A method of impact welding a cover plate to a component is provided as well as a support system for welding repair of hollow components.

Abstract: The inventions disclosed by this application are for a cladding apparatus, a cladding head, and a method of cladding a relatively planar solid object such as a boiler waterwall. Cladding of non-horizontal surfaces is complicated by the effects of gravity as melted clad material trends to runoff the surface before the cladding material bonds to the appropriate location. The disclosed inventions overcome these limitations by controlling the relative angle of application by either rotating the workpiece or the cladding head through a pre-programmed sequence. Also presented in a compact design for a laser cladding head that facilitates such cladding by minimizing movement of the laser fiber and improves cladding speed over irregular shaped objects.
