In recent days, the utilization of lightweight alloys for various applications has been
increased massively. Starting from the automobile industry, aerospace industry, and even in …

Advanced welding processes for structural materials are gaining increasing importance for
strategic applications in nuclear, aerospace, automobile, and defence sectors. These …

An innovative hybrid laser-arc welding technique has been developed for one-pass welding
of 25 mm thick steel plates. The parts to be welded were assembled into a butt joint …

Multi-pass narrow-gap welding of thick Inconel 617 plate was conducted with YLS-10000
fiber laser. The influence of different welding parameters on the joint geometry and defects …

How to control poor fusion of sidewall and interlayer in narrow-gap laser welding with filler
wire of thick plates is an unsolved problem. When the groove width changes in the direction …

Real-time tracking and alignment of the welding torch with the center of the weld seam are
critical for automatic root pass welding of medium-thick plates. However, assembly errors …

A defect-free welded joint of 100 mm-thick SUS 304 steel plates is produced by ultra-narrow
gap laser welding with filler wire in the laser conduction mode in 42 layers. The laser beam …

In this investigation, two laser-based welding techniques, autogenous laser welding (ALW)
and laser welding assisted with a cold wire (LWACW), were applied to join thick plates of a …

Austenitic stainless steel has many excellent properties and it has been extensively used in
rail transit trains. Ultra-narrow gap laser wire filling welding is the preferred welding method …

Abstract 6 mm thickness high strength low alloy (HSLA) steel butt joints were fabricated by
fiber laser welding. The influence of welding parameters on morphologies, weld process …
