Spatial beam oscillation during laser beam welding of aluminum to copper was investigated.
The beam was spatially oscillated perpendicular to the direction of feed in a sinusoidal mode.
The influence of the oscillation amplitude and frequency on the weld seam geometry and the
implications on the electrical resistance of the joints was investigated. It was found that spatial beam
oscillation allows to set the welding depth and seam width virtually independent of each other.
Furthermore, low welding depths into the lower copper sheet in combination with high ratios of
seam width at the interface of the two sheets to welding depth into the lower copper sheet result in
low electrical resistances of the welds. Low electrical resistances were found to correlate with high
mechanical strengths of the welds.
