When welding vertically with 7018 what direction should you go?

When weaving vertically up with a 7018 electrode, zigzag back and forth, and allow each puddle section to freeze in place in time to weld up to the next stair step. Hold the electrode slightly uphill, and keep a short arc to gain better penetration and fusion. During a weave, focus on welding the sides of the joint.

What positions can 7018 be welded in?

For an E7018 stick electrode maintain a good leading angle and “drag” the stick electrode along the weld joint. A 3 to 5 degree angle is ideal for vertical up welding, and employing a slight weaving technique works well in this position, too.

What is the best rod for vertical welding?

For vertical-up welding, the best rod is the E7018 because it deposits the strongest and most ductile weld metal. An E7018 can also fill the join faster than the other rods. For vertical-down welding, the best rod is the E6010 (and the E6011) because it deposits fast-freeze weld metal.

Why am I getting undercut on my welds?

Undercut can occur for several reasons: Excessive heat from high current and voltage settings. If the travel speed is too fast, the electrode moves away from the weld pool prematurely. If edges are not prepared properly dirt or grit on the welding surfaces tends to block heat transfer which can cause undercutting.

Can you run 7018 AC rods on DC?

7018 AC will burn fine on DC the pics posted of stick welding with the 200DX was with some old 7018 AC rod i had.

How do you prevent an undercut in 7018?

How to Prevent Undercut in Stick Welding: 12 Golden Tips

  1. Control Your Arc Length.
  2. Control Weld Angle.
  3. Reduce Current.
  4. Slow Down the Travel Speed.
  5. Reduce the Weave Width.
  6. Choose the Correct Welding Position.
  7. Consider Which Electrode You Are Using.
  8. Allow the Base Metal to Cool.

What Rod do I use to weld cast iron to steel?

There are two common types of Cast iron Welding Rod, Ferro-Nickel and Pure Nickel. Ferro-Nickel are typically 53% Steel and 47% Nickel. Ferro-Nickel Rods are cheaper than pure Nickel and are ideal for welding Cast Iron to Steel.
