Presented at ICALEO 2010
Laser polishing represents a new surface finishing technique for sculptured work pieces which offers shorter process times and lower costs in comparison to the predominantly used manual polishing. The technique is based on remelting a thin surface layer by laser radiation. The surface tension of the melt pool induces a reallocation of material from the peaks to the valleys, thus creating a polished surface.
When freeform surfaces are poli...$28.00

Presented at ICALEO 2010
Welding of copper is generally considered to be difficult, particularly due to its high heat conductivity. During welding with high-power lasers the low absorptance of the near and even more the far IR wavelengths means an additional hurdle. Resulting back reflections can be hazardous for optics, beam guidance and laser source. On the other hand copper and its alloys gain in importance e.g. in view of the comi...$28.00
