摘 要: 焊接曲轴是近代曲轴制造工艺中一个重要成就。采用窄间隙埋弧焊方法焊接曲轴,不仅保证了焊缝的强度和刚度,而且节省了材料、降低了焊接应力、减少了焊接缺陷。 Welding crankshaft is an important achievement in modem crankshaft manufacture process. Narrow gap submerged arc welding was used in crankshaft,which can not only ensure the weld strength and stiffness, but also saving material, reducing the welding stress and welding defects.
