Dec 18, 2018 · In the present investigation, titanium alloy Ti6Al4V of 1.4 mm thickness has been laser-welded in butt joint configuration using pulsed Nd:YAG laser system. The effects of heat input on weld bead shape, fusion zone width (top, middle, and bottom), heat-affected zone (HAZ) width (top, middle, and bottom), and fusion zone area have been studied. The microstructure and mechanical properties Effects of the laser parameters on the mechanical Dissimilar laser welding of AISI 304 and AISI 420 stainless steel sheets was performed with pulsed Nd:YAG laser so as to evaluate the temperature distribution, microstructure and mechanical properties of the welded zone. The effects of pulsed laser process parameters including (pulse duration, frequency, current, focal length and welding speed) on the fusion zone temperature variation were Enhancement Surface Mechanical Properties of 2024 Al Enhancement Surface Mechanical Properties of 2024 Al-Alloys Using Pulsed Nd:YAG Laser Cladding Raid M.Hadi P 1 P, Mahmoad Sh.

Microstructure and Mechanical Properties of Fe-36Ni and

High-quality joining of dissimilar alloys between Fe-36Ni alloy and 304L stainless steel is essential in the manufacturing of LNG tanker. In this study, lap joints of Fe-36Ni and 304L dissimilar alloys were fabricated by a pulsed gas tungsten arc welding (P-GTAW) process. The effects of low-frequency pulse on the appearance, microstructure and mechanical properties of the Fe-36Ni/304L lap Microstructure and mechanical properties of low industries. In this research S700MC steel is successfully welded using low power pulsed Nd:YAG laser and the microstructure and mechanical properties are investigated. It is shown that the average power and overlapping factor both affect the weld geometry. Full penetration with double-sided welding achieved on 2 mm thick plates autogenously. Microstructure and mechanical properties of low power Request PDF Microstructure and mechanical properties of low power pulsed Nd:YAG laser welded S700MC steel Thermomechanically controlled processed steels have gained attention increasingly by
