TL;DR: Pulsed Nd-YAG laser welding characteristics of Inconel 718 sheet material (2.mm thick) were investigated in this article, where Weld microstructures and room temperature tensile properties were evaluated.

TL;DR: In this paper, Nd:YAG laser drilling of 4 and 8mm thick sections of IN718 and Ti-6Al-4V materials has been investigated and relevant geometrical features of the drilled holes, like hole diameter and taper angle, have been comprehensively investigated.

TL;DR: In this paper, a typical cutting regime for pulsed Nd:YAG laser cutting of 1mm thick Hastelloy-X sheet has been constructed and explained in terms of extent of spot overlap.

TL;DR: In this paper, the authors used Taguchi design of experiments technique to study the effects of the above process variables on the quality of the drilled holes and ascertain optimum processing conditions for laser-drilled holes.

TL;DR: In this paper, the selective laser sintering (SLS) of iron powder has been investigated through a number of experiments statistically planned as per Taguchi L8 design, where seven input parameters, namely, laser peak power density, laser pulse on-time, laser scan speed, stepping distance (distance traveled between pulses), interval-spot ratio (ratio of laser scan line interval and laser spot diameter), size range of powder particles, and powder layer thickness, were selected for the investigation.
