一次双面成型熔剂层下自动电弧焊,是现代焊接技术中生产率高、既经济又有效的新型焊接方法,它可使厚度为3～12毫米板材的对接双面焊缝一次焊成,目前苏联已较广泛的在生产中应用。“红色锅炉工”工厂在制造长10780毫米、直径3060毫米、壁厚6毫米的圆筒形不锈钢容器时采用了这一先进技术,使每台容器的制造成本降低10000卢布。苏联各使用厂的生产实践证明,这种新的焊接法可提高劳动生产率1.5～2倍,熔剂和电能的消耗量降低一半,对于薄板的焊接可以免除一般自动焊时所不可缺少的、造价昂贵而带有熔剂垫的电磁平台。现将这种焊接方法的设备与工艺简介如下。
A double-sided flux layer automatic arc welding is a modern welding technology with high productivity, both economical and effective new welding method, which can make the thickness of 3 to 12 mm butt welded double-sided welding plate, the current Soviet Union Has been more widely used in production. The Red Boiler Works used this advanced technology to manufacture cylindrical stainless steel vessels of 10,780 mm in length and 3060 mm in diameter and 6 mm in wall thickness, reducing manufacturing costs by 10,000 rubles per container. Production practices at the factories in the USSR prove that the new welding method can increase labor productivity by 1.5 to 2 times and reduce flux and energy consumption by half. Welding for thin plates can eliminate the indispensable and expensive cost of general automatic welding Electromagnetic platform with flux pad. Now this welding method of equipment and technology are as follows.
