Role of Bead Sequence in Underwater Welding [PDF]
Materials, 2019 This paper presents examinations of the role of the bead sequence in underwater welding. Two specimens of wet welded layers made by covered electrodes with the use of normalized S355G10+N steel were welded by a reasonable bead sequence. For each specimen, metallographic macro- and micro-scopic tests were done.

Optimizing Welding Sequence and Improving Welding Process for Marine Thick-Walled Circular Pipes. [PDF]
Materials (Basel)To reduce welding deformation during the automated welding of thick-walled pipes in shipbuilding and thereby improve welding quality, a segmented multi-layer multi-pass welding sequence optimization and process improvement strategy is proposed. Firstly, based on a welding model for thick-walled pipes, a multi-layer multi-pass welding trajectory ...

Welding sequence optimization of plasma arc for welded thin structures [PDF]
WIT Transactions on The Built Environment, 2012 Dividing the weld path into multiple seams that are welded sequentially in a specific order is one of the most important and cost effective distortion and residual stresses mitigation strategies. This is particularly important for welding fabrication of thin structures.
