The invention provides a method and apparatus for forming a freeform metal structure by wire feed additive manufacturing. In accordance with the method, a holding structure is moved in at least one moving direction, the holding structure holding the metal structure. A metal wire end is fed along an area of deposition on the metal structure in the at least one moving direction. The metal wire end is heated to a melting temperature using a heat source, with the metal wire end as melted being deposited on the metal structure as a metallic build-up material. The metallic build-up material after heating and during the cooling is subjected in the at least one moving direction behind the area of deposition to at least one pulsed magnetic field using a magnetic coil arranged after the heat source, the at least one pulsed magnetic field effecting plastic deformation of the build-up material.

The present invention provides a method for preventing the forming of cracks and slowing the crack propagation in metallic airplane structural parts by laser shock peening with the following steps: Providing an airplane structural part having a crack; irradiating a first surface area of the airplane structural part close to the crack with a first pulsed laser beam having a first wavelength and a first pulsation frequency, wherein energy of the first laser beam is absorbed by the airplane structural part and a shock wave runs through the airplane structural part, which creates compressive prestressings in the airplane structural part.
