How to read Weld Symbols?

 

Weld symbols are a key part of welding documentation, and understanding How to read & Use Welding Symbols is critical for welders, Inspectors & Engineers.

To start learning, note that there are three main elements of a welding symbol:

1. Reference line (Mandatory part),
2. Arrow Line (Mandatory part), and the
3. Tail (Non-Mandatory part)

The reference line is a horizontal line that is used to align the other elements of the symbol. The arrow is used to point to the location of the weld, and the tail contains information about the type of weld, size, and other details.

Weld symbols can be simple or complex, depending on the information they need to convey. However, all weld symbols follow the same basic format.

By understanding how to read weld symbols, you can ensure that you are accurately interpreting welding documentation.

Welding symbols or Weldment Symbols are the integral part and the basic requirements for fabrication as they provide vital information for the welding joint location, weld size (throat or leg length, depth of penetration) & length, weld type & quality requirements for the fabrication or construction drawing.
