What is the approximate tensile strength associated with the E6010 electrode?

• A. 70 ksi
• B. 50 ksi
• C. 60 ksi
• D. 40 ksi

Answer: (C)

Electrode classifications encode the strength of the weld deposit. The number in the electrode code that denotes tens of ksi tells you the approximate tensile strength the weld is designed to achieve. For E6010, the “60” means about 60 ksi. That’s the expected strength of the weld metal, regardless of other properties like coating or welding position, which are indicated by the remaining digits but don’t change the strength rating. So the approximate tensile strength is around 60 ksi. Higher numbers would indicate stronger deposits (for example, around 70 ksi), while lower numbers would indicate weaker deposits (around 50 or 40 ksi).
