粗丝窄间隙混合气体保护自动焊,是厚板焊接的先进工艺之一。我厂用这种方法焊接了脱硫吸收水洗塔(筒体拼板,材质是西德HⅡ,相当20g,板厚46毫米)、高压釜(筒体拼板,材质是西德FG39,相当50MnV,板厚26毫米)、发汗罐(管板拼板,材质是A3F,板厚40毫米)及400米~3球罐(上下球罐顶拼板,材质是FG39,板厚48毫米)等产品。所有的焊缝均为平板对接。绝大多数焊缝一次合格率达95％以上。设备
Thick wire narrow gap gas mixture protection automatic welding, welding is one of the advanced plate technology. I plant in this way welded desulphurization absorption washing tower (cylinder puzzle, the material is West Germany H, quite 20g, thickness 46 mm), autoclave (cylinder puzzle, the material is West Germany FG39, quite 50MnV, Thickness of 26 mm), sweat cans (tube board puzzle, the material is A3F, thickness 40 mm) and 400 m ~ 3 ball tank (up and down the ball tank top puzzle material is FG39, thickness 48 mm) and other products. All welds are flat butt. The vast majority of welds a pass rate of 95% or more. equipment
