A welding symbol has three parts: Reference line: this is the main part of the symbol and it's function is to carry or provide all the information on the weld to be made. Arrow: this is what is used to point the reference line to where you need to weld. Tail: This is used to provide additional but important data as wells as information needed to complete the weld.
A finish symbol (when used) shows the method of finish, C represents chipping, M means machining, and G indicates grinding, not the degree of finish. How contour and finish symbols are applied to a welding symbol is illustrated in Figure 7-23.
Welding standards, engineering drawings, and the elements of the weld callout are explored. Understanding the standardized welding language between design engineering and manufacturing will limit uncertainties after the product is passed onto someone else.
Sheet Metal Fabrication. Sheet Metal Fabrication consists of any of a variety of processes that are used to convert a raw piece of sheet metal into a specific shape, configuration or assembly. This can happen through cutting specific features into the part, bending or forming it into different shapes, or connecting multiple pieces together.
This engineering drawing present weld type symbols and fillet weld symbols. The weld type symbol is typically placed above or below the center of the reference line, depending on which side of the joint it's on. The symbol is interpreted as a …

Welding Symbols are a graphical way to convey information about a welding joint. Instead of using an arrow and saying 'weld here', a weld symbol carries more useful information that can be easily understood by the welder, engineer, foreman, supervisor and architect. Hence, Welding Symbols are widely used in engineering drawings by welders and …

5 Parts of the Fillet Weld. If you will look at the graphical symbol of a fillet weld, you will see that there are five elements or parts to a fillet weld. These elements include the throat, leg, face, toe, and root. The deepest penetration of weld is called the root. The root is at the hypotenuse's opposite angle.

The welding symbol (fig. 3-2) is a method of representing the weld symbol on drawings. The assembled "welding symbol" consists of the following eight elements, or any of these elements as necessary: reference line, arrow, basic weld symbols, dimensions and other data, supplementary symbols, finish symbols, tail, and specification, process ...
Studying this guide to welding symbols will help ensure you are one step closer to acing your next exam. Welding Symbols (with Charts) Some welding symbols look complicated, but when they are broken down, you will see they're quite simple. The welding symbols are illustrations of the pre-weld joint looking side on, as through a cross-section.

1.3 Symbol sizes are shown in the figures as values propor-tional to the letter 'h'. The letter 'h' represents the predominant character height on a drawing. If a symbol dimension is shown as 1.5h, and the predominant character height on the drawing is to be 3mm, then the symbol dimension is 4.5mm (1.5 x 3mm).
