A production supervisor observes a welder using a new batch of SMAW electrodes that appear to have been stored incorrectly, showing signs of moisture absorption. The project is structural steel for a building under CSA W59. What is the most appropriate action the supervisor should take regarding these electrodes?

Question: A production supervisor observes a welder using a new batch of SMAW electrodes that appear to have been stored incorrectly, showing signs of moisture absorption. The project is structural steel for a building under CSA W59. What is the most appropriate action the supervisor should take regarding these electrodes?

Answer options:

• Allow use, but increase welding current to compensate for moisture. ✅ Issue new electrodes from a properly stored batch or bake the current batch according to manufacturer's specifications.
• Ignore it, as minor moisture absorption does not significantly affect structural welds.
• Discard the electrodes immediately without further action.

Correct answer: Issue new electrodes from a properly stored batch or bake the current batch according to manufacturer's specifications.

Explanation: Moisture absorption in SMAW electrodes, especially low-hydrogen types, can lead to hydrogen-induced cracking in welds, compromising their integrity. CSA W59 emphasizes proper electrode storage and reconditioning (baking) as per manufacturer specifications to prevent this. Increasing current is not a solution, and ignoring it is unsafe.
