摘要： The invention relates to a machining head with integrated powder supply for deposition welding using laser radiation. A machining head in accordance with the invention can in particular be used for deposition welding at a high deposition rate. In the machining head in accordance with the invention, the laser radiation is directed to supplied powder and to a material surface with a focal spot. The powder supply takes place symmetrically to the axial feed direction with a plurality of channels arranged oppositely. The channels are aligned at an obliquely inclined angle so that powder discharged from them is supplied into the focal spot of the laser radiation from two mutually oppositely disposed sides over the total width of the focal spot with respect to the axial feed direction.

摘要： An apparatus and method are provided for laser deposition welding of powdery welding material. The powdery welding material is conveyed via a nozzle coaxial with respect to a laser beam directed in a focused manner with a constant focal length onto a processing region through the nozzle onto the processing region. Optical elements are arranged in a laser optical unit for the shaping and guidance of the laser beam. The laser optical unit is attached to a processing head and can be moved with the processing head parallel to the laser beam by a first drive. The plane of the focal point can thereby be changed with respect to the surface. The nozzle can be moved independently of the laser optical unit parallel to the optical axis of the laser beam by a second drive.

摘要： The invention relates to a method for producing shaped bodies or applying coatings on workpieces. The aim of the invention is to produce shaped bodies which are structured in an almost arbitrarily three-dimensional manner or contoured coatings are allowed to be formed on most different workpieces wherein simultaneously the required time and energy will be reduced in comparison with conventional procedures. According to the invention, a shaped body will be built-up in layers or a coating that consists of at least two individual layers will be applied on a workpiece. For this, a platform whereon the shaped body will be built-up or the workpiece is held in a clamping device which is movable within at least two axes in relation to two different sources of heat. The layers which are located inside the shaped body or which are arranged towards the surface of the workpiece will be formed by means of plasma arc weld surfacing or using an inductor having a greater layer thickness and track gauge of the individual layers, and at least one external cover layer having a smaller layer thickness and track gauge will be formed by means of laser beam weld surfacing.

摘要： The invention relates to a machining head and to a process for the surface machining of workpieces by means of a laser beam, in which coating, alloying in the area close to the surface or dispersion of a peripheral zone of the base material with powder particles can be carried out using a pulverulent filler supplied. The invention is intended to make it possible to maintain, independently of direction, a virtually constant mass flow rate of the powder supplied, the intention being to form a uniform hollow powder jet. According to the invention, this object is achieved by the fact that in a housing of the machining head a turbulence chamber is formed, into which a powder-gas flow is introduced at least via one entry opening and the powder-gas flow is directed through a conical annular gap, as a hollow coaxial jet, as is the laser beam guided through the housing, onto a workpiece surface, and stabilizing passages, which are aligned parallel to the longitudinal axis of the laser beam, are present in a radially symmetrical arrangement between the turbulence chamber and the annular gap.

摘要： The invention relates to a method for applying a coating by means of plasma spraying to a substrate, in which method the beam of a laser is additionally used, it being possible to coat a very wide variety of substrates in order, in particular, to improve the properties on the substrate surface. Moreover, the method according to the invention is to achieve a high coating rate and, in addition to advantageous adhesion and density of the layer, also to influence in a controlled manner the layer structure which is being formed. The procedure is that at least one continuous laser beam is directed through the spray jet, with a predeterminable interaction time, directly onto the surface of the substrate or the surface of a layer which has already been applied thereto, so as to initiate the melting thereof
