| Description: | Universal 7018-1 is a general purpose electrode that allows you to tackle a wide variety of welding projects with ease. You will get superior weldability from this low hydrogen, mild steel electrode that provides you with excellent start and restart capabilities in addition to a smooth and virtually spatter free arc. Universal 7018-1 has a very flat bead shape with a fine ripple appearance. The weld puddle smoothly washes into the sidewalls with no undercut. Slag removal is one of the best and in many cases is self-peeling. Universal 7018-1 also has the ability to operate smoothly even when the welding surface is somewhat dirty or rusty. Universal 7018-1 is designated as a low moisture absorbing product and can be exposed to higher temperatures and humidity for over 8 hours and meet AWS requirements. Extremely high impact levels are available with Universal 7018-1 even at -50F giving it the AWS E7018-1 designation. |
