AB Plates joining is one of the first stage at large vessels manufacturing line, processconditioning the whole shipbuilding production. Laser Arc Hybrid Welding (LAHW) processis nowadays providing promising results for large thickness naval steel, being primarily used forwelding plates with thicknesses between 6 to 15 mm, reaching up to 51 mm. In addition to thishigh penetration ability, LAHW allows increasing the production rates. Therefore, this technologyis proposed as an alternative to conventional welding processes in shipbuilding, as it integratesthe advantages of laser and arc welding, providing high process stability, high welding speed andpenetration, narrow weld beads with a low heat input and good metallurgical properties. The presentreview reports the most representative investigation regarding the use of this technology to joinlarge thickness flat panels of naval steel. It includes a summary of the most influential processvariables, equipment characteristics, material properties, naval regulations, as well as microstructuralcharacterisation and mechanical properties of joints. This review is thought to help readers fromdifferent backgrounds, covering from non-expert on welding or on naval sector, to industrial LAHWapplicators and researchers. The industrial need of performing one single pass procedure to assurehigh quality welds of high thickness is suggested as one of the key aspects for future investigations.
