Influence of welding sequence on welding distortions in pipes [PDF]
International Journal of Pressure Vessels and Piping, 2008 This paper presents a three-dimensional thermo-mechanical analysis to investigate the effect of welding sequence on welding deformations in pipe-pipe joints of AISI stainless-steel type. Single-pass TIG welding with V-joint geometry in pipes having a diameter of 274 mm and a thickness of 6.2 mm is studied here.

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 ...

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.

Facta Universitatis, Series: Mechanical Engineering, 2020 In this paper the influence of tack welds distribution and welding sequence on angular distortion of the Tungsten Inert Gas (TIG) welded joint was tested. Additionally, the effect of welding current on angular distortion was assessed. For research X2CrTiNb18 (AISI 441) stainless steel (2.5 mm thick) was chosen.
