One of the most pivotal factor during construction of modern ships is to utilize high strength steels in order to obtain substantial weight reduction. The genuine joint capability, easy process, lowering fabrication price, as well as effective metal joining method is crucial in order to the production of engineering and structural components. Nowadays, there is great demand concerning lightweight but strong material joints which assists in ship construction. The weldment joint properties mainly depend on the filler composite of material. This paper studies about the strength of welded joints which utilizes different nanoparticles as filler material and judged with respect to different loading conditions through the conventional butt welding joint in ship structure. The AH36 steel is one of the standard high strength steels used for shipbuilding. The investigation of nanoparticle as filler material was carried out through finite element method, whereas conventional welding filler material grade 308LER was tested experimentally. Finite element method is utilized for analyzing mechanical properties of AH36 Butt joint by using nanoparticle (TiO2, ZrO2 etc.) as filler material.
