Sections through Webs and Ribs Webs and ribs are added to some objects to increase the part’s strength and rigidity. Figure 5-27 shows how ribs and webs are represented in sectional views. Rules on Reading Prints There is no one best way to read a print or draw- ing. Most welders come up with their own method. The following rules are suggested to help you get started. Eventually, you will develop a method best suited to your own needs. ❍ Carefully review the print. ❍ Study one view at a time. Identify surface limits and lines that describe the intersection of surfaces. This will help you to visualize the shape of the object. ❍ Establish sizes from the dimensions. ❍ Review the other information (notes, title block, revisions, etc.) on the print. ❍ Determine what your responsibilities will be in producing the object and the sequence you will follow in performing the operations. ❍ Do not be afraid to ask for help if you do not understand something on a print. A mistake caused by not understanding something can be very costly to your employer and may cause injury to someone using the product at a later date. ❍ Practice print reading until it becomes sec- ond nature to you. Figure 5-25. With a broken-out section, only a small portion of a sectional view will adequately show essential information. Figure 5-27. Note this section through a web or rib. Section lines are not drawn through webbed or ribbed areas. Figure 5-26. A conventional break allows elongated objects to be shortened so a larger scale can be used to show details more clearly. 39.50
