华南工学院刘世民等在《焊接》杂志1982年第4期上著文介绍了有关低碳钢水下焊焊条的研究进展。水下涂药焊条湿法焊接,至今焊条的工艺性能和接头的机械性能还是比较差。从国内外情况来看,接头的抗拉强度和塑性,一般只有陆地上焊接时的80%和50%左右。 South China University of Technology, such as Liu Shimin in the “Welding” magazine in 1982 the fourth on the article introduced the research progress of low carbon steel underwater welding electrodes. Underwater coating electrode wet welding, so far the electrode of the process performance and mechanical properties of joints is still relatively poor. Judging from the situation at home and abroad, the tensile strength and plasticity of joints are generally only about 80% and about 50% when welding on land.
