What type of electrode is best suited for steel that has a tendency to develop porosity and underbead cracking?
a-fill freeze
b-low hydrogen
c- fast fill
d-fast freeze
Answer is b-low hydrogen (These electrodes offer good deposition rates and good penetration, which means welding operators can add more weld metal into the joint in a given time than many other stick electrodes also help eliminate issues like porosity at the start of the weld.)
