Welding is an essential skill used in many industries around the world. In fact, welding is estimated to be involved in 90% of all US manufacturing.
But what is the secret behind welding? It all starts with a welding symbol. Welding symbols are used to communicate essential information about the weld being assembled.
Over the course of this article, we’ll take an in-depth look at what a welding symbol is, as well as what information you can learn from it. According to the American Welding Society, there are over 700 standard welding symbols used in a variety of industries, making them an integral part of the welding process. So, read on to learn more about the secrets of welding symbols!
What is a Welding Symbol?
Welding symbols are graphical representations of the weld that are used to provide information about the type of weld, the size and shape of the weld, and other relevant details about the weld joint.They are also used to convey specific instructions about how the weld should be made. Welding symbols are used in engineering drawings and blueprints to accurately convey the welding process.
Components of a Welding Symbol
A welding symbol is composed of two main parts, the arrow and the tail.The arrow is the main part of the symbol that originates from the reference line and points to the location of the weld. The tail provides all the additional information necessary to make the weld, including size, mixing ratio, root gap, etc.
Layout of a Welding Symbol
A welding symbol is laid out as follows:- Reference Line – This is a solid line that indicates where the weld will start. It is usually horizontal or vertical, depending on the orientation of the object being welded.
- Arrow – This is the directional element of the symbol and is the main part of the symbol.
It is the portion that originates from the reference line and points to the position of the weld.
- Tail – This is the supplemental information section of the symbol.
The tail contains all the additional information necessary to accurately create the weld joint, such as size, shape, material types, etc.

Uses of Welding Symbols
Welding symbols are used to accurately convey the welding process, which helps to simplify the fabrication process for welders. They are used in engineering drawings and blueprints to accurately convey the welding process.Welding symbols allow for clear and concise communication between designers and welders, and allow for welders to work with greater ease and without having to constantly refer back to the drawings. This helps to save time and eliminates errors due to miscommunication.
