摘要
铸钢件是船舶建造常用的基本材料,通常用在尾部挂舵壁分段、舵分段等位置。在极地甲板运输船的建造过程中,低温铸钢件的焊接工艺是一个全新课题,其冲击韧性要求不小于27 J的接头性能在国内尚无先例,本项目通过对坡口角度的调整达成改善焊接接头冲击韧性的目标。
Steel castings are materials commonly used in rudder and its holder blocks for shipbuilding industry. During the building of the polar class heavy transport deck carrier, welding of low-temperature steel castings with weld impact toughness not less than 27 J is a new subject for shipyard and it is perfectly achieved by adjusting bevel angle.
