Welding Consumables for Pipeline Market

Pipelines have gained widespread popularity worldwide as a secure and cost-effective method for transporting oil and natural gas across long distances, and their laying distance is expected to increase in the future. Girth welding is the primary method used for laying pipelines, which involves connecting steel pipes on-site using various welding consumables such as stick electrodes, solid wires, flux-cored wires, and TIG rods and wires. Welding consumables used for recent pipeline laying work must demonstrate low-temperature toughness and high tensile strength. Furthermore, there is a growing trend toward automating girth welding to improve the efficiency of the laying process, which necessitates the development of welding consumables suited to automated welding. This paper introduces welding materials that meet these needs, including actual joint performance. © 2023 Kobe Steel Ltd. All rights reserved.
