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 the AWS classification for mild - steel electrodes (e.g., E7018 - 1 H4R), the number after the first letter (E in this case) represents the minimum tensile strength. For example, in E7018 - 1 H4R, the "70" indicates a minimum tensile strength of 70,000 psi (or 70 ksi).

Answer:

Minimum tensile strength in KSI
