摘要： PURPOSE:To provide a reciprocating oscillation type laser beam oscillator which is easily controllable, small in size, easily light-condensable, compatible with a high output laser, and low in running cost. CONSTITUTION:A movable reflection mirror 38 and an electromagnetic oscillator 66 are supported by a rotary supporting member 62 which is provided rotatably around a rotary axial center A that is positioned inside a face orthogonally crossing an oscillating axial center B; and the movable reflection mirror 38 is rotated around the rotary axial center A by revolving the rotary supporting member 62 by a motor 70. When the movable reflection mirror 38 is oscillated around the oscillating axial center B by the electromagnetic oscillator 66, the irradiation point of a laser beam L on a work to be machined is moved in reciprocation by a prescribed frequency, and the movable reflection mirror 38 is also rotated around the rotary axial center A by the motor, changing the reciprocating moving direction of the irradiation point of the laser beam L on the work to a desired direction.

摘要： PURPOSE:To facilitate the adjustment of a stroke sensor and simplify the structure thereof. CONSTITUTION:A resonance circuit is one which is equipped with a coil 23 and a condenser 31 and, in turn, this coil 23 is one that expands or contracts with the stroke of a shock absorber. Since inductance in the coil 23 varies according to this expansion or contraction, impedance in the resonance circuit 32 varies. An oscillation circuit 33 generating ac voltage of constant frequency is connected to the resonance circuit 32. This frequency is such equivalent to resonant frequency at the time when coil length becomes minimum. In addition, a smoothing circuit 34 converting AC voltage into dc voltage is connected to this oscillation circuit 33.

摘要： PURPOSE: To enable the adjustment of a thickness in the width direction of a build-up welding layer by slantingly oscillating a high energy heat source to the longitudinal direction at the time of executing the build-up welding in the longitudinal direction by the irradiation of the high energy heat source while supplying the build-up welding material on a base material. CONSTITUTION: A laser beam L is condenced with a convex lens 3 and irradiates a valve seat part 2 around the port 1a of a cylinder head 1 through an oscillating mirror 4. The valve seat part 2 is horizontally rotated with a rotary table and the build-up welding material M is supplied to this treating surface from a build-up welding material supplying device 6, and shield gas is supplied from a shield gas supplying device 7 to execute the build-up welding in the longitudinal direction. At this time, the laser beam L irradiates slantingly to the treating surface and oscillates with a fixed width in a prescribed direction by a galvano-motor 5. By this method, the time lag is generated at the irradiating time of the laser beam L in the width direction of the working build-up welding layer, and the thickness in the width direction of the build-up welding layer can be adjusted.

摘要： PURPOSE:To prevent a crack from being caused in a surface build up welding layer by forming nonmagnetic alloy as a first build up welding layer and forming alloy which is made amorphous by rapid cooling coagulation thereon as a second build up welding layer and impressing high-intensity energy on this layer to perform rapid redissolution and rapid coagulation and forming an amorphous pattern. CONSTITUTION:Nonmagnetic alloy free from martensitic transformation is formed as a first build up welding layer 5 on an iron-based alloy base body 1 which causes martensitic transformation. An alloy layer 6 is formed between both. Alloy which is made amorphous by rapid cooling coagulation is formed as a second build up layer 10 thereon. An alloy layer 11 is formed between both. High-intensity energy (laser) 13 is impressed on the second build up layer 10 to perform rapid dissolution and rapid recoagulation and an amorphous pattern 14 is formed. Thereby the strength difference of an output signal is made large in detection of the magnetic characteristics in the amorphous part or the crystalline part on the surface build up welding layers.
