Study on process parameter of high performance laser cutting machine tool for copper sheet
A high performance NC laser cutting machine tool for copper sheet is designed, emphasis discussing the components of NC laser cutting machine tool and design points. Performance of high power semiconductor pulse micro-cutting of copper sheet is studied and several key parameters are given by changing assistant gas and process parameters. The experimental results show that the best cutting quality can be obtained when argon is used as assistant gas, and oxygen is on the contrary. Also, in a certain range, improving laser power and cutting speed can help in decreasing laser cutting gap, minishing heat affected area, and achieving better cutting quality.

Welding with combination of two CO2-lasers - Advantages in processing and quality
Welding with high power CO2-lasers has proved to be an accepted technology for joining in engineering and automotive industry. Combining two beams that originate from two separate lasers on a specific gantry system offers a large range of new parameters, which can be used for optimization of process stability and efficiency as well as of quality of the weld seam. With a special focusing device an independent variation of the focal conditions of each beam can be achieved. The superposition of the beams was investigated with respect to their effects upon the weldability of several materials and improvements of the welding process itself.Welding with high power CO2-lasers has proved to be an accepted technology for joining in engineering and automotive industry.
