Piping and Instrument Diagram Standard Symbols Detailed Documentation provides a standard set of shapes & symbols for documenting P&ID and PFD, including standard shapes of instrument, valves, pump, heating exchanges, mixers, crushers, vessels, compressors, filters, motors and connecting shapes.
Read OnThe finish symbol reveals how to finish a weld. For example the following letters are used to convey this information on a symbol: C = chipping; M = Machining; G = Grinding; For example there is a G, as shown below, so the welder needs to grind the weld to create the contour that is needed, and the actual contour is to be 'flush'.
Read OnClick the Annotate tab Symbols panel Surface Texture. Select an object to attach the surface texture symbol to. If you attached the symbol to a line, in the drawing area, specify the start point for the leader. If you attached the object to an arc, circle, ellipse or spline, skip to the next step. Specify one or more points to define the vertices of the leader, and then press ENTER.
Read OnThis page shows a list of GD&T symbols and associated symbols used by ISO and ASME. "Learning GD&T From Scratch," provided by KEYENCE, walks you through the basics of geometric dimensioning and tolerancing, datums, and measurements by coordinate measuring machines. It also introduces techniques for visitors who want to learn more.

Read OnThe idea was to represent rough or first machining operation by one triangle (triangle symbolizes the turning cutting tool). Two triangles meaning two passes of the tool and hence finer finish. Normally four triangles require a grinding operation and a roughness of between 32-16 microinches RMS.

Read OnSpacer – This symbol indicates the type and the dimension of the spacer that is inserted between the welded pieces. Weld all around – It signals that the weld is to be made over the entire circumference. Flag symbol – Field weld/Made on site. Contour – These symbols designate the final weld end product contour.
Read OnLay is generally produced by the manufacturing process and can be parallel, perpendicular, circular, crosshatched, radial, multi-directional, or isotropic (non-directional). We will discuss the symbols and interpretation of lay in the Symbols section below. Waviness. Waviness is the term used for the most broadly spaced surface finish variations.

Read OnSurface finish refers to the process of altering a metal's surface that involves removing, adding, or reshaping. It is a measure of the complete texture of a product's surface that is defined by three characteristics of surface roughness, waviness, and lay. The surface roughness is the measure of the total spaced irregularities on the surface.
Read OnThe fillet weld symbols are usually triangular in the cross-section, and its shape is usually not an isosceles or right triangle, but it is a triangle either way. Most of the common weld types in the industry are used when the joint has two members joining together to create an intersection of 90 degrees.
