Question

how can you identify a low hydrogen electrode?

ask the welder what it is
read the classification numbers painted on the covering near the stub end of the electrode
ask the welding foreman
look at the completed weld and identify the type of electrode by the weld deposit

Explanation:

Identify the standard identification method

Using the Low Hydrogen Electrodes and AWS Electrode Classification knowledge points

• Electrodes are standardized by the American Welding Society (AWS).
• The classification numbers (such as E7018) are printed or painted directly on the flux covering near the stub end of each electrode.
• Reading these printed classification numbers is the only reliable, direct physical method to identify a low-hydrogen electrode before welding.

Answer:

• (A) Ask the welder what it is
• (B) Read the classification numbers painted on the covering near the stub end of the electrode (Correct answer)
• (C) Ask the welding foreman
• (D) Look at the completed weld and identify the type of electrode by the weld deposit
