Numerical simulation of laser beam welding of Ti6Al4V sheet
This paper was aimed to report the 3D finite element analysis simulation of laser welding process of Ti6Al4V 1.7 mm sheets in butt joint in order to predict the temperature distribution, hardness, and weld geometry. The butt-joint welds were made using CO2 laser with the maximum power of 2.2 kW in the continuous wave mode. A part of the experimental work was carried out to verify the weld geome...
متن کاملDevelopment of a fast position-sensitive laser beam detector.
We report the development of a fast position-sensitive laser beam detector. The detector uses a fiber-optic bundle that spatially splits the incident beam, followed by a fast balanced photodetector. The detector is applied to the study of Brownian motion of particles on fast time scales with 1 A spatial resolution. Future applications include the study of molecule motors, protein folding, as we...
متن کاملDevelopment and application of new high-power laser beam sources
The actual market volume of high-power lasers for manufacturing is dominated by diffusion cooled CO2 laser systems at the multi-kW range and lamp pumped Nd:YAG laser systems at the kW range. Substituting the lamps by diodes the Nd:YAG laser in rod design entered the market as diode pumped solid state laser of the first generation. With output powers up to 6 kW the diode pumped rod is used in in...
متن کاملDevelopment and Testing of a Refractive Laser Beam Shaping System
A lens system for shaping a laser beam profile has been designed, built, and tested. It consists of two plano-aspherical lenses which convert a Gaussian input beam into a uniform irradiance output beam. The optical design is based on solving differential equations expressing conservation of energy and constant optical path length condition as the beam passes through the system. Experimental res...
متن کاملTemperature Distribution of Particles in a Laser Beam
This article studies the particle temperature distribution depending on the laser radiation power and the particle’s trajectory and velocity. The uneven heating of particles moving in the laser radiation field is identified. The regimes of laser heating without melting, with partial melting, and with complete particle melting are considered.
