我厂生产的储液罐产品(如图1所示),在焊接椭球形封头的环形焊缝时,采用图2所示的环形充气衬垫,达到了单面钎焊双面成型的目的,不需要再从桶的内侧进行钎焊,减轻了焊工的劳动强度,提高了劳动生产率,并保证了产品质量。现将这种充气衬垫简单介绍如下: 结构见图2,在等分圆的三块弧 I produced the tank products (as shown in Figure 1), the welding seam elliptical head of the annular weld, the use of the ring shown in Figure 2 inflatable cushion, to achieve a single-sided brazing forming the purpose , No need to braze from the inside of the barrel, reducing the labor intensity of the welder, improving the labor productivity and ensuring the product quality. Now this kind of inflatable cushion brief introduction is as follows: The structure is shown in Fig. 2, in the circle of three arcs
