영문 초록

In this study, the purpose of this thesis was to investigate the welding characteristics and the mechanical properties behavior of 784Mpa high-strength steel, commonly using truck, farming machine, heavy equipment etc. Weldments according to the welding conditions on changes welding specimens opening angle in 784Mpa high-strength steel welding is important to acquire more knowledge. Structural discontinuities such as joints and in part due to repeated loading and fatigue crack growth are more likely to crash, accident welding conditions depending on the skill of welders according to the strength of welds is true that a lot of factors that reduce a lot of research on this progress and form, but the geometry and load conditions due to the combined effects, including a lot of issues still remain to be solved in this study the following facts. Butt joint of welding material at plate thickness 12mm atos 784Mpa high-strength steel in the form 4pass, 20ℓ/min, 50˚, 24V/200A is good in the welding specimen of Indication on the radiograph
