This guide outlines recent advances in the various methods of laser technology and appropriate manufacturing applications. Each process has unique requirements and matching the laser source to the project is essential for developing a robust solution.

A novel approach in the field of narrow gap laser welding produces superior weld joint quality, especially the configuration of weld toe, which has a positive effect on fatigue life.

This article describes how shielding gas composition, either argon or nitrogen, affects the hardness, tensile strength, and toughness of high-power, high-brightness laser welds made on various base materials, including A508 forging steel, 316L stainless steel, Inconel 690, and solution-annealed IN718.
