The “Laser-assisted double wire with non-transferred arc surfacing process (LDNA)” is characterized by an electric arc burning between the filling wires. The molten filler material is fed to the substrate surface by gravity and is shaped by a laser beam. In this work, the influence of laser parameters on seam geometry and dilution is investigated. The investigations include a linear and convex pendulum form, a focal length of 300~mm and 400~mm, an oscillation frequency of 10~Hz and a disc laser using a wavelength of 1,030~nm with a power of 1,000~W and 1,400~W. Two 316L filling wires with 1.2~mm and an AISI1024 substrate with 20~mm are used. The change in the dilution and the welding geometry is determined.
