Abstract (en)
[origin: WO9908829A1] A pair of coated components are laser welded to one another by initially forming protuberances on one of the components. The protuberances maintain juxtaposed surfaces separated and the components are then laser welded to one another. The separation of the surfaces vents vapor generated by the coating.
