摘要

水下焊接包含水下干法焊接、局部干法焊接和湿法焊接三类

其中湿法焊接因其简单方便受到了广泛关注。介绍不同水下焊接方式的特点

并重点介绍水下湿法焊接在专用焊条研制、电弧稳定性分析以及焊缝成形建模三个方面的研究发展历程及最新研究成果

提出还需在湿法焊接专用传感器的研制、电弧燃烧过程及机理分析等方面进一步开展深入探索

以推动湿法焊接的高质量发展。

Abstract

There are three kind of welding method of underwater welding

they are underwater dry welding

underwater local dry welding and underwater wet welding

in which

the wet welding has been gained compressive attention for its easy and convenient operation. The properties of different wet welding are introduced at first. And then

the research development and achievements of wet welding are discussed from three aspects

which are welding rod study

arc stability study and welding shape modeling. At last

some suggestions are proposed that we should increase the study on the wet welding special sensors and arc discharging mechanism

and so as to promote high quality development of wet welding.
