It includes a summary of the most influential process variables, equipment characteristics, material properties, naval regulations, as well as microstructural characterisation and mechanical properties of joints. The present review reports the most representative investigation regarding the use of this technology to join large thickness flat panels of naval steel. Therefore, this technology is proposed as an alternative to conventional welding processes in shipbuilding, as it integrates the advantages of laser and arc welding, providing high process stability, high welding speed and penetration, narrow weld beads with a low heat input and good metallurgical properties. In addition to this high penetration ability, LAHW. Laser Arc Hybrid Welding (LAHW) process is nowadays providing promising results for large thickness naval steel, being primarily used for welding plates with thicknesses between 6 to 15 mm, reaching up to 51 mm. Plates joining is one of the first stage at large vessels manufacturing line, process conditioning the whole shipbuilding production. The mechanism for changing failure location can be related to the strain rate dependence of the plastic deformation behaviors of microstructures in various regions across a joint. And the failure location changed from the base metal to the softened heat-affected zone (HAZ) as strain rate increased. The distance of the tensile failure location from the weld centerline decreased obviously with the increase of strain rate. The strain rate sensitivity of the deformation behavior of DP780 steel joints was mainly dependent on the change of deformation behavior and its mechanisms of base metal at various strain rates. The strength of DP780 steel joint increased with increasing strain rate, while the ductility decreased first with increasing strain rate from 10-3 to 101 s-1, and then increased up to a strain rate of 102 s-1. The results showed that the deformation behavior of laser welded joints was more sensitive to strain rate as compared to base metal of DP780 steel. present work aimed to study the effects of strain rate on tensile properties and deformation behavior of laser welded DP780 steel joints. The use of DP steels in automotive industries involves laser welding, which would lead to changes in local material properties and create potential safety and reliability issues under dynamic loads. View full-textÄual phase (DP) steels have good combinations of strength and ductility, and are being increasingly used in vehicle body structures to meet enhanced government regulations and safety standards. However, selecting among the proposed procedures the ones that better match the good practice of the finite element analysis and considering the effects of misalignments and irregularities of the typical shipbuilding practice, estimates of the fatigue strength in substantial agreement with the experimental results can be obtained. However, it was possible to highlight that, especially for complex geometries, such kind of local approaches is not easy to implement and that the guidelines of IIW do not give a definite method for the estimate of the fatigue strength of the joint. The calculations, carried out according to the standards but with different approaches and interpretations, showed a significant dispersion of the results. Large scale fatigue tests of the captioned joint carried out in the Ship Structures laboratory of DINAV allowed a subsequent comparison: it is worth noting that the numerical analyses were conducted without knowing the tests results. Moreover, the alternative method proposed by Xiao e Yamada in 2004 has been applied. The study has been carried out following the guidelines suggested by the International Institute.of Welding (IIW).

The structural detail is a butt joint between HP (bulb) stiffeners, strengthened by aflat patch welded onto the top of the HP profiles the bulbs are beveled but not welded. the applicability of such method to a rather complex geometry. The aim of this work is to apply the structural stress approach to a welded joint used in shipbuilding and in ship repairs and to verify. Local approaches are nowadays a common engineering practice for the evaluation of the fatigue strength of welded joints and regulations describe their application, addressing designers' calculations carried out by means of widely applied numerical simulations.
