埋弧焊是在焊剂层下通过电弧进行焊接的一种方法。 具有焊接质量稳定、无电弧、焊接生产率高、烟尘少等优点,是管段制造、压力容器、箱形梁等钢结构生产中的主要焊接设备。
Submerged arc welding is a method of using electric arc to weld under the flux layer,With the advantages of stable welding quality,high welding productivity,no arc light and less smoke,it has become the main welding equipment in the production of steel structures such as pressure vessels,pipe segment manufacturing and box-type beams and columns.
应用范围Scope of application:
半自动埋弧焊小车主要应用于钢结构、造船、桥梁和压力容器等行业。
Semi-automatic submerged arc welding trolley is mainly used in steel structure,shipbuilding,bridge and pressure vessel industries.
主要特点Main features:
1、生产效率高:一方面焊丝导电长度缩短,电流和电流密度提高,从而大大提高了电弧溶深和焊丝溶敷效率。(一般不开坡口单面一次溶深可达20mm)另一方面由于焊剂和溶渣的隔热作用,电弧上基本没有热的辐射散失,飞溅也少,虽然用于熔化焊剂的热量损耗有所增大,但整体热效率仍有较大提高
High production efficiency:on the one hand,the length of wire conduction is shortened,and the current and current density are increased,thus greatly improving the arc penetration and wire deposition efficiency(Generally do not open groove one-side solution depth up to 20mm).On the other hand,due to the heat insulation effect of flux and slag,there is basically no heat radiation loss on the arc,and there is little spatter.Although the heat loss for melting flux is increased,the overall thermal efficiency is still greatly improved
2、焊缝质量高:熔渣隔绝空气的保护效果好,焊接参数可以通过自动调节保持稳定,对焊工技术水平要求不高,焊缝成分稳定,机械性能比较好
High quality of welding seam:the protection effect of slag against air is good,and the welding parameters can be kept stable through automatic adjustment,with low requirements on the welder's technical level,stable composition of welding seam and good mechanical performance
3、良好的工作条件:除了减轻手工焊操作的劳动强度外,它没有弧光辐射,这是埋弧焊的独特优点
Good working conditions:in addition to reducing the labor intensity of manual welding,it has no arc radiation,which is the unique advantage of submerged arc welding
4、自动焊接:焊接参数可通过自动调节保持稳定。与手工电弧焊相比,焊接质量对焊工技艺水平的依赖程度可大大降低
Automatic welding:the welding parameters can be maintained stable through automatic adjustment.Compared with manual arc welding,the dependence of welding quality on welder's skill level can be greatly reduced
