Abstract
The minimum laser pulse energy necessary to obtain a sufficient penetration depth of the welding seam has been determined as a function of pulsewidth for a variety of sheet metals. Thermophysical and optical properties like thermal conductivity, thermal diffusivity, melting temperature, latent heat, and reflectivity are suitable parameters to explain measurement results. Strength tests lead to possible ranges for suitable pulse energies, pulsewidths and pulse overlaps within adjustment can be chosen under the viewpoint of economy of operation.
