本文介绍了六种目前国内外应用最广泛、收效较大的简易衬垫单面自动焊工艺。各种工艺的衬垫原理、结构各不同,但都能满足以下条件:1.能使反面焊缝成型良好;2.防止焊穿;3.与坡口反面的贴紧程度良好;4.能保持衬垫形状不变。其安装和固定衬垫的方法有:1.利用钢板本身的重量(压紧);2。用斜楔(定位焊)和夹马;3.使用螺旋夹具;4.使用磁铁装置;5.直接把衬垫焊到钢板坡口反面。
This paper introduces six kinds of simple single-sided automatic welding technology which is the most widely used and effective at home and abroad. A variety of process liner principle, the structure of different, but can meet the following conditions: 1. Can make the reverse weld good shape; 2. To prevent welding wear; 3. And the groove on the reverse of the close degree of good; 4. Can Keep the pad shape the same. The installation and fixing of the liner are: 1. The use of the weight of the plate itself (compression); Using a wedge (positioning welding) and clamping the horse; 3. using a helical clamp; 4. using a magnet device; 5. welding the liner directly to the opposite side of the bevel of the steel plate.
