Question: What does the number '70' in an E7018 SMAW electrode classification indicate?
Answer options: ✅ Minimum tensile strength in ksi (thousands of pounds per square inch)
- Minimum yield strength in psi
- Percentage of elongation
- Maximum current setting in amps
Correct answer: Minimum tensile strength in ksi (thousands of pounds per square inch)
Explanation: For AWS/CSA electrode classifications, the first two or three digits, in this case '70', indicate the minimum tensile strength of the deposited weld metal in thousands of pounds per square inch (ksi). So, 70 ksi means 70,000 psi.
