Welding Symbols. One of the most important welding symbols is the fillet weld. This weld is an extremely common practice in fabrication and field work. This symbol is characterized by a right triangle which is the lateral shape of a real fillet weld. Fillet welds are generally performed on a 90 degree joint of 2 perpendicular pieces of metal.

A good design drawing can indicate all the details needed to produce a mechanical CNC milling part in an easy way. Because there is no large space on a drawing to contain all the text to illustrate the image, abbreviations, and symbols are often used in engineering drawings to communicate the characteristics of the product to be manufactured.

Common additional symbols used with groove welds are the melt through, backing bar, and back weld and backing symbols. In the case of melt through, the groove is reinforced with a weld on the back side of the joint welded from the opposite side. The melt-through shape is a black half circle (see Figure 4).

Yet another symbol on Figure 7-22 is the field weld symbol, a black flag that points toward the tail of the welding symbol. For welds that cannot be made in the shop, for size, transportation, constructability, or other reasons, this symbol directs the welder to make the weld in the field, which could be "in situ" or on site.

Blast clean or grind contact surfaces prior to welding: Remove loose mill scale, paint, galvanizing, grease, oil, rust, moisture, or other materials. Grind joints to remove pitting and irregularities. Bring parts into close contact: Separation greater than 1/16 inches requires an increase in the fillet weld leg equal to the separation distance.
