Adds manufacturing tabs to detailed parts at plate edges. You can place tabs of various types.
Plates might have sharp corners or bent edges that could become deformed during fabrication, erection or assembly. Manufacturing tabs are additional material around such areas. Tabs are applied when seams or plate edges cross at angles that would produce acute angle corners. Welding often damages or melts off these sharp corners, so the tabs are added to protect the sharp part corners. These tabs are trimmed off after welding.
Tabs are introduced when cutting out a plate from a flat sheet, or padding material that is added later. Either way, tabs modify the manufactured part’s outer contour.
A tab could have several shapes, depending upon where they are located. For example, in order to protect a circular opening through which a seam passes, you could protect the opening edge with tabs of different shapes as shown below.
