E stands for electrode,70 is the tensile strength,1 is for all positions of welding,8 AC or DC reverse polarity and 18 also combine for lime flouride coatings.
E6013
The designation E6011 means: E=electrode 60=60,00p.s.i.tensile strength as deposited 1= all position 1=coating make up
no 7018 is for carbon steel 9018 for chrome 308 is for stainless
70 -70 THOUSAND POUND RATING i.e tensile strength 1 - all position 8 - it contains moisture so pre heating is required
There is a coating on electrode. It absorb moisture from an atmosphere. To remove moisture from it, we have to back that electrode up to 300 ' C. If we dont heat this electrode, there is a chance to get discontinuity in welding. Ketan Baraiya
Low Hydrogen? It is a welding electrode that has controlled Hydrogen levels for use in SMAW i.e E7018. Not to be confused with a low hydrogen processes like GMAW and GTAW
E stands for Electrode,70 stands for tensile strength,1 stands for position of welding that is for all positions 8 stands for flux coating.
