TL;DR: In this paper, the possible welding distortion during the fabrication of I section welded structure in cantilever beam of a jack-up drilling rig was studied with prediction and mitigation, and some mitigation practices such as application of inverse distortion, optimization of welding sequence and constraint methods, were conducted and examined.

TL;DR: In this article, a Computational approach based on inherent deformation was proposed, and its framework and application were introduced in detail, typical fillet welded joint was experimentally conducted and its solid elements FE model was numerically examined with experimental validation.

TL;DR: In this article, two High Tensile Strength Steel (EH47) plates with thickness of 70mm were butt-welded together by multi-pass Submerged Arc Welding (SAW), also the hardness and welding residual stress were investigated experimentally.

TL;DR: Based on the welding inherent deformation theory, typical welded joints of two major structures were systematically classified with the different material, thickness, welding condition and joining form; and the relationships between welding heat input and inherent deformations were also presented as mentioned in this paper.

TL;DR: In this article, an out-of-plane bending deformation with different patterns can be observed and their magnitudes were also measured by three-coordinate measuring machine (TMM).
