A method and apparatus for forming an object by additive layer manufacturing. The method comprises: a) applying, by a heat source (4), heat to a portion of a surface of a workpiece (1) sufficient to melt said portion; b) adding material to the melted portion and moving the heat source (4) relative to the workpiece (1) whereby progressively to form a layer of material (10) on the workpiece (1); c) cooling the formed layer (10) to bring at least part of the layer (10) to a state of crystallisation, there producing a modified workpiece; d) peening, using a plurality of independently controllable impact treatment devices (7), the modified work-piece so as to plastically deform the cooled at least part of the layer (10); and repeating steps a) to d) as required whereby to form the object.

According to one implementation, a laser peening processing device includes a laser peening processing device includes a laser oscillator, a nozzle and an inclining structure. The laser oscillator emits laser light. The nozzle condenses and irradiates the laser light toward a surface to be processed of a workpiece, with injecting liquid toward the surface to be processed. The inclining structure inclines at least one of the nozzle and the workpiece to make an injection direction of the liquid be different from a normal direction of the surface to be processed. The air bubbles arising by at least one of collision between the liquid and the surface to be processed and shock by irradiation of the laser light on the surface to be processed are flowed in a direction depending on an inclined direction of the surface to the injection direction of the liquid.

A remanufacturing method for a metal part having a damage. The damage groove is divided into a number of levels, and the groove bottom is treated by absorption layer-free laser shock peening to remove surface impurities and to refine surface-layer crystal grains. Then a cladding layer is formed by laser cladding. The process is repeated until the groove is completely filled by the cladding layer to higher than the surface of the metal part and the cladding layer higher than the surface is cut by a mechanical processing and polished, and the upper surface of the laser cladding layer is subjected to large-area overlapped laser shock peening.
