Abstract
⺠Laser welding: direct absorption at the keyhole surface is modelled. ⺠Surface waves heavily modulate direct absorption compared to a smooth capillary. ⺠Waves rapidly cause local shadowing regions, redistributing the energy. ⺠10 μm-lasers loose much of their stable high direct absorption at wavy surfaces. ⺠1 μm-lasers experience an absorption increase at wavy surfaces.
