Unibraze 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. Unibraze 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. Unibraze 7018-1 also has the ability to operate smoothly even when the welding surface is somewhat dirty or rusty. Unibraze 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 Unibraze 7018-1 even at -50 deg F giving it the AWS E7018-1 designation
- Superior weld appeal
- Promotes arc time for increased productivity; weld easily, reducing welder fatigue
- Effortless starts and restarts
- No starting porosity; ideal for tacking; increases welding productivity
- Low moisture absorption rate
- Reduces worry of moisture pick-up resulting in low hydrogen cracking; required less trips to the oven for dry electrodes; increase quality and reliability of weld
- Low spatter
- Ideal for all positions; produces good looking welds; reduces clean-up time
- Good wetting action
- Produces a nice flat bead contour; prevents cold laps; eliminates undercutting
- Very stable arc
- Easy to control; runs smooth in all positions with excellent vertical-up capability
- Easy slag removal
- When used for tacking with Smoothcor wires, Smoothcor slag over tacks is easy to remove
- Hardness: 162 BHN
