Laser transmission welding of transparent plastics parts in micro technology
Most welding processes for plastics do not meet the special demands of micro technology. Laser transmission welding, however, features distinctive advantages like low mechanical and thermal load of the joining parts. Hence it is particularly suitable for the welding of micro plastics parts. Certain optical properties of the components to be welded are needed though. While one of the welding par...
متن کاملA Real-Time Spectroscopic Sensor for Monitoring Laser Welding Processes
In this paper we report on the development of a sensor for real time monitoring of laser welding processes based on spectroscopic techniques. The system is based on the acquisition of the optical spectra emitted from the laser generated plasma plume and their use to implement an on-line algorithm for both the calculation of the plasma electron temperature and the analysis of the correlations be...
متن کاملLASER WELDING - Literature Review
Lasers are now being used in the automotive industry to produce seam or stitch welds, as alternatives to conventional resistance spot welding, which are used extensively for attaching auto-body panels to subassemblies. The advantages of laser welding over resistance spot welding result from the smallness of the laser spot size, the large penetration depth of the weld into the material and the r...
متن کاملLaser Scanning Technology for Bridge Monitoring
After the collapse of the Minnesota I-35 bridge (August 1, 2007), there has been a renewed interest in the US to enhance bridge infrastructure monitoring (Liu et al., 2009). Other than developing traditional inspection and material testing techniques, there has been also increased discussions about possible applications of Commercial Remote Sensing (CRS) technologies for civil infrastructure mo...
