This research was conducted as a joint research project with the Shipbuilding Research Center of Japan and other shipyards, with the organizing committee set up at the Japan Ship Technology Research Association (JSTRA). The authors express their appreciation to the National Maritime Research Institute for the fatigue test of cruciform joints and to the JFE Steel Corporation for providing steel plates.

A joint industrial research project focusing on the applicability of laser-arc hybrid welding in the construction of general merchant ships was organized by the Japan Ship Technology Research Association and supported by the Nippon Foundation and the Shipbuilding Research Centre of Japan. The research was conducted from 2012 to 2014. The achievement of this JIP was presented in PRADS 2016 [3] and the guidelines of laser-arc hybrid welding for hull construction was published by Class NK [4] according to the JIP results. However, several research subjects that could not be addressed in this research project were pointed out. Therefore, new members joined the JIP and a new JIP worked to solve these problems. In this presentation, an overview of the main research results of the second phase JIP are introduced.

N2 - The application of advanced welding technologies is important for improving the efficiency of hull construction processes and reducing production costs. Laser-arc hybrid welding technology, which combines the advantages of laser and normal arc welding, is of high quality and is expected to improve productivity. The Japan Ship Technology Research Association has organized the joint industry project in collaboration with a university, a classification society and some shipyards to apply this technology in the construction of general merchant ships, in which the plate thickness of the main structural member is thicker than passenger ships and high speed craft. The overview of the first phase JIP results were introduced in PRADS 2016. In this presentation, an overview of main research results of the second and third phase JIP, which are listed below, are introduced.
