Abstract：The understanding of distribution analysis and existing form of alloying elements near fusion line was helpful to confirm the influence of welding materials on the properties of fusion area such as hardenability tendency. By optimizing the working parameters of instrument, the determination method of Al, Ti, V and Ni in low alloy steel by LA-ICP-MS was established. The proposed method was applied to the study on change tendency of element contents （Al, Ti, V and Ni） in welding line and adjacent base metal. The results showed that, the content of these alloying elements had obvious transition interval （95-360 μm） near fusion line. Moreover, the larger the difference of content between welding line metal and base metal was, the wider the transition interval in welding line was.
