What is the identifying color band found on 2% thoriated tungsten?

• A. Red
• B. Blue
• C. Green
• D. Yellow

Answer: (A)

The identifying color band on 2% thoriated tungsten electrodes is red. This color coding is essential for welders, as it allows them to easily identify the type of tungsten they are working with and its specific characteristics. Thoriated tungsten is known for its excellent performance during welding processes, particularly in arc stability and higher current ratings. The red band indicates that this tungsten contains a small percentage of thorium oxide, which enhances its performance by providing better electron emission. This is vital for achieving strong, clean welds. Understanding these color codes assists welders in selecting the appropriate electrode for specific applications, leading to improved efficiency and quality in welding tasks.
