Question: When welding cast iron, which of the following filler metals often contains a significant amount of nickel and is used to produce machinable welds?

Answer options:

  • E7018 ✅ ENiFe-CI
  • ETr-1
  • ER70S-6

Correct answer: ENiFe-CI

Explanation: ENiFe-CI electrodes (or similar nickel-iron electrodes) are specifically designed for welding cast iron. The high nickel content in these fillers helps to ensure that the weld deposit remains ductile and machinable, accommodating the brittle nature of cast iron. E7018 and ER70S-6 are for steel, and ETr-1 is not a standard filler metal classification.
