Comparative study of pulsed Nd:YAG laser welding of AISI

In the present work, comparative studies on laser welding of similar metal of AISI 304SS and AISI 316SS have been conducted forming butt joints. A robotic control 600 W pulsed Nd:YAG laser source has been used for welding purpose. Comparative welding performance of CO2, Nd:YAG, and Jun 29, 2009 · These characteristics have found the repetitively pulsed Nd:YAG laser many applications in welding of precision electronic parts. The welding performance of high-power Nd:YAG lasers is compared to that of the CO 2 laser in Figure 1. The laser labeled "Hobart" was designed by a company called Martek under US Government contract to have a very small focus so the laser would be useful for welding Effects of weld cross-section profiles and microstructure Mar 01, 2014 · In this study, the influence of weld cross-sectional profiles and microstructure, under different welding conditions, was investigated on the mechanical properties of pulsed Nd:YAG laser-welded joint of Ti6A14V alloy. The V- and H-shaped weld cross-section profiles were obtained under low and high heat input, respectively. The microstructure in the fusion zone (FZ) of V- and H-shaped

Finite Element Analysis of Nd:YAG Pulse Laser Welding for

The objective of this study is to investigate the influence of surface roughness on the morphology of aluminum 6061-T6 alloy after irradiation with a Nd:YAG pulsed laser. PAPER OPEN ACCESS Optimizing pulsed fiber laser Apr 07, 2020 · comparative study between pulsed Nd:YAG laser welding and pulsed-TIG welding of titanium alloy sheet and found that less distortion and better mechanical properties were obtained in Parametric analysis of the pulsed Nd:YAG laser seam May 15, 2000 · A set of pulsed laser parameters is now defined that will help to clarify the approach used in this work:P P =average peak power (kW)=pulse energy (J)/pulse duration (ms); P D =average peak power density (kW/mm 2)=average peak power (kW)/spot area (mm 2)=APPD; P M =mean laser power (kW)=pulse energy (J)×pulse repetition rate (Hz), where T P is the pulse duration (ms), E P the pulse energy (J), PRR the pulse repetition rate (s 1), T F the pulse-to-pulse

Results:One month after the last laser treatment, final total VSS analysis of treated sites by PDL and long-pulsed Nd:YAG laser revealed significant improvements (p < 0.001), whereas the average percentage of improvement in the total VSS was 55.14% for PDL and 65.44% for Nd:YAG laser. However, there were no statistically significant Comparative analysis of pulsed Nd:YAG laser welding of Abstract The current study investigates the comparative study of similar pulsed Nd:YAG laser welding of 304L and 904L stainless steel. In the present study both austenitic stainless steel (304L) and super austenitic stainless steel (904L) are laser welded at 5 mm/s scanning speed, 25 Hz pulse frequency and 0.75 mm laser spot diameter. The ultimate tensile strength of both laser welded
