摘要
采用蒙乃尔薄板套筒包裹的方法对海洋工程用碳钢结构在海水溅射区进行防腐保护,并对蒙乃尔合金薄板的焊接性、焊接接头形式的设计及焊接工艺的制定进行了探讨.结果表明,采用手工钨极氩弧焊进行焊接施工的焊缝外观合格,力学性能符合ASMEⅨ标准中相关章节的要求.宏观金相观察结果表明,焊缝中未见气孔、未熔合及裂纹等缺陷.
The anticorrosion method of splash zone for offshore oil engineering carbon steel structure using the method of Monel plate sheathing is introduced,and the weldability of Monel plate,field joint design and welding procedure specification are discussed.The results show that the appearance of welds is acceptable which were done by using Gas Tungsten Arc Welding process,the Mechanical properties of joint conform to the requirements of the relevant sections in ASMEⅨstandards.The Macro metallographic observation results show that there is no porosity and incomplete fusion and cracks and other defects in the weld.
