| 摘 要： | 文中通过对水下焊接电弧光谱的采集和分析，研究了清水、硼酸溶液、LiOH溶液、硼酸+LiOH混合溶液等不同介质的水环境对水下焊接电弧等离子体成分以及温度的影响，并对陆上焊接和水下焊接的电弧等离子体成分和温度进行对比分析.结果表明；不同的水下环境介质对水下焊接电弧等离子体成分以及温度几乎无影响.但水下焊接与陆上焊接相比，其电弧等离子体成分比陆上焊接明显增加了H和O元素.此外水下焊接过程中，由于水环境的影响，使水下焊接电弧温度低于陆上焊接.

| Abstract: | By collecting and analyzing the underwater welding arc spectrum, the influence of the different water environment media such as clear water, boric acid solution, LiOH solution, and boric acid+LiOH mixture, on the composition and temperature of underwater welding arc plasma were studied. In addition, the composition and temperature of arc plasma during on-land welding and underwater welding were compared and analyzed. The results indicated that the effects of water media on underwater welding arc plasma are almost negligible. However, the H and O in arc plasma composition of underwater welding are significantly more than those in the on-land welding arc. Owing to the water environment, the arc temperature of underwater welding was lower than that of on-land welding arc. |
