Question

identify the 70 in the aws classification for mild steel electrodes. hydrogen level in ml/100 g welding position minimum tensile strength in ksi indicates impact requirements electrode type of coating and current indicates requirements of absorbed moisture test e7018 - 1 h4r

Explanation:

In AWS classification for mild - steel electrodes like E7018 - 1 H4R, the number 70 indicates the minimum tensile strength of the weld metal in KSI (kilopounds per square inch).

Answer:

C. Minimum tensile strength in KSI
