在焊接大直径的碳钢或不锈钢等薄壁容器的过程中,我们常常会遇到两个问题而影响薄壁容器的焊接质量和外观质量,一是即使严格地控制落料尺寸,但在两筒节对焊时仍然容易错位,二是在焊接过程的作用下,薄板容易变形。为了解决上述两个问题,本文介绍一种薄壁容器焊接中的工艺垫环——槽铜垫环。 1.糟铜垫环的结构槽铜垫环如图1所示,由5~#槽钢形的铜件(我们称之为“槽铜”)制成槽平面向外的圆环形
In the welding of large-diameter carbon steel or stainless steel and other thin-walled containers in the process, we often encounter two problems that affect the thin-walled vessel welding quality and appearance of the quality of the first, even if strictly controlled blanking size, but in two Butt tube welding is still easy to misplaced, the second is the role of the welding process, the sheet easily deformed. In order to solve the above two problems, this article describes a process of welding thin-walled container gasket ring - groove copper ring. 1. The structure of the bad copper ring The copper ring of the copper ring shown in Figure 1, made of 5 ~ # channel-shaped copper pieces (we call the “copper”) made out of the groove plane outward circular
