To avoid issues with electrode performance, care must be taken to prevent which problems?

• A. Weak or missed welds
• B. Improved surface finish
• C. Faster cycle times
• D. Increased electrode life

Answer: (A)

Electrode performance hinges on achieving a stable arc, proper heat, and clean deposition so the weld fuses fully across the joint. Weak or missed welds are the direct sign that something in the electrode or process isn’t performing correctly—whether it’s moisture in the coating, contamination, incorrect shielding, or improper current, travel speed, or joint preparation. When electrodes are kept dry, the right type is used, the current and travel speed are appropriate, and joints are clean and well fit, fusion is complete and deposition is consistent, preventing those weak or missing sections. Other options describe favorable outcomes, not problems to prevent. Improved surface finish, faster cycle times, and longer electrode life are all possible results of good electrode performance, rather than issues that need to be avoided.
