NettetThe use of lasers in materials pro-THE AUTHOR cessing is increasing, and in particular with the availability of more brilliant laser sources, like disk and fiber lasers, new pro-cesses and applications in laser beam welding become of interest. To take full advantage of these new capabilities the accurate tool of a high-brilliant laser NettetContact Us. An important feature of any laser beam is its state of polarisation. This identifies the direction, which is always at right angles to the direction of propagation, in which the electric field is vibrating. This vibration can be simple, having only one direction along the beam path (linear polarisation) or it can be complex. example of library file in cNettet10. apr. 2024 · Laser welding can be automated through robots, creating clean welds that require little to no post-weld processing. LBW equipment is initially expensive and the process isn’t suitable for plastics with thicknesses above 0.5 inches (12.7 mm). Laser beam welding can sometimes lead to porosity and brittle results. example of licensed operating system
