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.
How do you prevent an undercut on 7018 vertical?
Here they are:
- Control Your Arc Length.
- Control Weld Angle.
- Reduce Current.
- Slow Down the Travel Speed.
- Reduce the Weave Width.
- Choose the Correct Welding Position.
- Consider Which Electrode You Are Using.
- Allow the Base Metal to Cool.
What is the best rod for uphill welding?
The 6011 and the 6010 rods are great for uphill welding and the only rods that can give excellent results downhill.
When welding in the overhead position the electrode should be?
The electrode should be held almost perpendicular to the weld axis for overhead welding. A travel angle of only 5°–10° is suggested.
How should the electrode be held when making an uphill weld?
The electrode centerline should be directly above the weld line. The electrode and torch should be inclined (tipped) 5°–15° in the direction of travel. This is a drag travel angle. On thin metals, a push travel angle is used.
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.
What is the best welding rod to use on 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.
What welding rod is good for vertical welding?
But especially important for welding in the vertical orientation. 7018, 7024, and 6010 electrodes may all seem like good choices, but you should typically use the 7018 for general purpose steel plate welding. 6010 rods require more skill than 7018’s when welding vertically.
