摘要： An assembly for producing a weld coupling a first part of a workpiece to a second part of the workpiece. The assembly comprises a first incoherent light source that generates incoherent light energy and a first negative waveguide having an input end and an output end, the incoherent light energy from the first incoherent light source and that reflected by the first reflector entering the first negative waveguide at the input end, passing through the first negative waveguide and exiting the first negative waveguide at the output end. The first negative waveguide having a non-conical longitudinal cross section producing a non-circular weld zone.

摘要： An optical scan system welds or marks a part by directing an optical beam onto the part at a sufficient energy density level to weld or mark it. A method of controlling a pattern where the part is to be exposed to the beam at the sufficient energy density level includes disposing a waveguide between the part and an optical source of the optical scan system to prevent areas of the part that are not to be welded or marked from being exposed to the beam at the sufficient energy density level to weld or mark them, allowing the areas to be welded or marked to be exposed to the beam at the sufficient energy level. In an aspect, the waveguide prevents the beam from being reflected in an undesired direction. In an aspect, the waveguide redirects the beam from the areas of the part that are not to be welded or marked to areas that are to be welded or marked to concentrate the energy on the areas to be welded or marked. In an aspect, a dissipative waveguide dissipates energy of the beam in the areas of the part that are not to be welded or marked so that those areas are not exposed to the beam at the sufficient energy density level.
摘要翻译：光学扫描系统通过将光束以足够的能量密度水平引导到部件上来焊接或标记部件以焊接或标记。控制要以足够的能量密度级别将部件暴露于光束的图案的方法包括在光学扫描系统的部件和光源之间布置波导以防止部件的不被焊接的区域或标记为以足够的能量密度水平暴露于梁以焊接或标记它们，允许焊接或标记的区域以足够的能级暴露于梁。在一个方面，波导防止光束在不期望的方向上被反射。在一方面，波导将来自未被焊接或标记的部分的区域的梁重新定向到要焊接或标记的区域，以将能量集中在待焊接或标记的区域上。在一方面，耗散波导耗散在不被焊接或标记的部分的区域中的光束的能量，使得那些区域不以足够的能量密度水平暴露于光束。
