摘要： A laminate is formed by overlapping at least a part of a first member and at least a part of a second member. The first member and the second member are joined by irradiating the laminate with a laser. The first member contains aluminum. The second member contains copper. The second member includes a first main surface and a second main surface. The second main surface is an opposite surface of the first main surface. A contact portion is provided due to contact of the first main surface with the first member. The second main surface is irradiated with the laser. A temperature of the contact portion is equal to or higher than an eutectic point temperature of Al and Cu and lower than a melting point of Cu.

摘要： Provided is a powder overlay nozzle that can increase the quality of an overlay layer formed on processing portion of a workpiece, and that can greatly increase workpiece productivity and maintainability. The powder overlay nozzle includes an inner nozzle member including a laser passage for passing laser beam, and an outer nozzle member externally fitted on the inner nozzle member. Between the inner nozzle member and the outer nozzle member, a discharge space for passing powder is formed. The outer nozzle member includes a supply channel for supplying the powder to the discharge space in a direction inclined with respect to an axis L of the powder overlay nozzle.

摘要： Provided is a powder supply device that can stably supply powder from a main hopper to a powder supply means including a sub-hopper without requiring component replacement and the like. The powder supply device is provided with: a first piping that guides powder accumulated in a main hopper downward; a second piping that is connected to the first piping at a lower end portion thereof while intersecting with the first piping, and that guides the powder guided by the first piping to a sub-hopper; and a switching valve that pressure-feeds the powder temporarily deposited while forming an angle of repose at an intersecting portion of the first piping and the second piping, to the sub-hopper.

摘要： A laser cladding apparatus includes a powder supplier to supply metal powder to a portion to be processed, a laser to irradiate the portion to be processed with laser so as to melt the metal powder for cladding, and a controller. The powder supplier includes a gas pressure gauge, and the controller stores, as an initial value, a gas pressure value measured by the gas pressure gauge when the metal powder supplied by the gas pressure reaches the portion to be cladding-processed. In operation after storing the initial value, the controller sets, as a reference time, timing when the gas pressure gauge measures a same pressure as the initial value, and outputs a start signal for laser irradiation to the laser based on the reference time.
