Oil tank welded rib's section structure

The utility model relates to an oil tank welded rib's section structure. It includes butt fusion end and socket end, butt fusion end position in socket end top, and the first notch of A style of calligraphy is offered to the lower surface of butt fusion end, and the second notch of A style of calligraphy is offered to the upper surface of socket end, and the open -top's of first notch contained angle is the obtuse angle, and the open -top's of second notch contained angle is the obtuse angle, and the width of butt fusion end is lighter than the width of socket end. The A style of calligraphy notch of all offering through butt fusion end and socket end, welding be by notch pass through gradually pressure and adhesion stress when having increased the welding to the mode on summit of the point in the outside, and vibrations and frictional force during simultaneously better elimination welding make butt fusion end and socket end reach better welding and fuses the effect, satisfy the burst strength requirement of
