A welder has substituted an e7014 electrode for the specified e7018 (low hydrogen) electrode for welding new A36 steel to existing gr 30 (older) steel. AWS A5.1 shows that the E7014 and E7018 have similar strength properties but the E7014 has no charpy v notch limits, unlike the E7018. Also E7014 can be susceptible to hydrogen embrittlement of the welds. The welds are fillets joining pieces less than 3/4" thick. The welds are fillets, 3/8" max to 5/16" min. The loads are static. The welds have been visually inspected and look ok, no cracks visible. Has anyone any experience about using E7014 in structural applications? All comments appreciated.
