The Evolution and Distribution of Microstructures in High-Energy Laser-Welded X100 Pipeline Steel [PDF]

Materials, 2019
High-energy beam welding was introduced for pipeline steel welding to reduce pipeline construction costs and improve the efficiency and safety of oil and gas transportation. Microstructures and their distribution in X100 laser-welded joints, which determine the joints’ strength and toughness, are discussed in this paper.
