Abstract
The Arctic region is expected to play an extremely prominent role in the future of the oil and gas industry as growingdemand for natural resources leads to greater exploitation of a region that holds about 25% of the world's oil and gasreserves. It has become clear that ensuring the necessary reliability of Arctic industrial structures is highly dependent onthe welding processes used and the materials employed. The main challenge for welding in Arctic conditions is preventionof the formation of brittle fractures in the weld and base material. One mitigating solution to obtain sufficiently lowtransitiontemperatures of the weld is use of a suitable welding process with properly selected parameters. This workprovides a comprehensive review with experimental study of modified submerged arc welding processes used for Arcticapplications, such as narrow gap welding, multi-wire welding, and welding with metal powder additions. Case studiescovered in this article describe welding of Arctic steels such as X70 12.7-mm plate by multi-wire welding technique.Advanced submerged arc welding processes are compared in terms of deposition rate and welding process operationalparameters, and the advantages and disadvantages of each process with respect to low-temperature environment applicationsare listed. This article contributes to the field by presenting a comprehensive state-of-the-art review and casestudies of the most common submerged arc welding high deposition modifications. Each modification is reviewed indetail, facilitating understanding and assisting in correct selection of appropriate welding processes and processparameters.
