Abstract
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.
