摘　　要：水下焊接技术是海洋管线、海洋平台、船舶、核电设备维护及抢修等领域的关键技术.水下局部干法焊接具有焊接效果好、成本低的优点,在水下焊接技术中具备非常广阔的发展前景.目前主要有水帘式及钢丝刷式水下局部干法焊接、排水罩式水下局部干法焊接和气室式局部干法焊接,作者提出了一种旋转叶片式水下局部干法焊接方法,该方法同主流的排水罩式或者气室式水下局部干法焊接技术相比最大的优点是省去了排水罩或气室等附加装置,简化了焊炬结构,同时省去了对排水罩或气室密封的要求.Underwater welding technology has become a key technology in the fields of maintenance and repairs of marine pipelines,offshore platforms,ships,nuclear power equipment.Underwater local dry welding sprang up in the 1970s.Due to its advantages of good welding effect and low cost,it has a very broad development prospect in underwater welding technology.At present,there are three main underwater local dry welding methods:water curtain type and wire brush type local dry underwater welding,drainage cover type local dry welding and gas chamber type local dry welding.
