摘要:: 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。
The article introducesg portable indirect automatic welding processes with backing，At pre sent, such welding processes are being widely and effectively used at home and abroad Although each of them has own backing principle and structure.al]of them can satisfy with following condition 1 .good weld appearance on opposite side;2.burn through prevented:3.close attachment wi t h another side of bevel:4.unchanged shape of the backing. The methods for installating and fixing the backing a re 1 .utilizing the Weight of steel plate and compressing tightly;2.using oblique wedge and jig:3 using sprial clamp and m agneti c device 4.welding the backing directly to the another side of bevel
