The invention provides a ship acute angle welding structure and a welding method thereof. The ship acute angle welding structure comprises a first splicing plate, a second splicing plate, a first acute angle plate, a second acute angle plate and a middle transition plate. The edge of the second splice plate is aligned with the edge of the first splice plate; one side of the splicing part of the first splicing plate and the second splicing plate is inserted into the acute-angle end of the first acute-angle plate; the other side of the splicing part of the first splicing plate and the second splicing plate is inserted into the acute angle end of the second acute angle plate; the middle transition plate is arranged in a center hole in the middle position defined by the first splicing plate, the second splicing plate, the first acute angle plate and the second acute angle plate. The acute angle smaller than a certain angle is converted into a welding joint with a large angle, stress concentration is reduced, and the technical problem that in the prior art, follow-up work such as flaw detection is needed for welding at the intersection of the acute angle, and consequently the cost of a welding structure and method in the prior art is high is solved.

    本发明提供了一种船锐角焊接结构及其焊接方法,所述船锐角焊接结构包括第一拼接板和第二拼接板,以及第一锐角板和第二锐角板、中间过渡板;所述第二拼接板与所述第一拼接板的边缘对齐;所述第一拼接板和所述第二拼接板拼接部分的一侧插入所述第一锐角板的锐角一端;所述第一拼接板和所述第二拼接板拼接部分的另一侧插入所述第二锐角板的锐角一端;所述中间过渡板设置于所述第一拼接板和所述第二拼接板,以及所述第一锐角板和所述第二锐角板围合中部位置的中心孔。通过将其小于一定角度锐角转化为角度较大的焊接接缝,减小应力集中,有助于解决现有技术中在锐角交汇处焊接需要探伤等后续工作,导致现有技术的焊接结构和方法成本较高的技术问题。
