Description
SQ-7018 is a general purpose, low hydrogen electrode for welding 490MPa class high tensile steel. E7018 has a very good deposition rate, producing steady arc with low spatter and medium penetration.
Key Feature
Improved coating integrity
Extreme bendability
60% less moisture pickup vs. competition
Reduction of arc starting porosity
Clear puddle and a smooth arc
