Effective throat: Extends from the hypotenuse to the root of the weld (see Figure 8-3). When using metric units on fabrication drawings, the units are typically given in millimeters (mm), centimeters (cm), or meters (m). Once students have a complete understanding of welded assembly prints, the next three models build skill in understanding revolved views and welded assemblies containing both fillet and groove welds, as well as welds involving pipe and plate. What is the total weight of part number 1? Figure 5-9 and Figure 5-10 show how the typical basic thread designations for both U. and metric threads are shown on drawings.
