7010 welding rod overview

If you are looking to weld carbon steel or low alloy steel sheets, there are a number of electrodes you can use. The 7010 welding rod is one of these electrodes. The 7010 will particularly be useful when you are welding piping in a high-pressure and high-temperature environment.

This high cellulose electrode can be used in all positions and is known for its fast freeze weld puddle. Let’s take a mode detailed look at the 7010 electrode and its properties.

All About the 7010 Welding Rod

This is a high cellulose electrode that can be used in all positions. It has a minimum tensile strength of 70,000 PSI. It is used for welding low alloy steel and is known for its deep penetration and fast freezing weld puddle.

Because of this, the electrode is a perfect choice for making vertical down welds. As for polarity, it can be used with both DCEP and DCEN. The amperage to use with this electrode will depend on the diameter of the rod.

A 3/32 inch electrode will use an amperage of between 50 to 90 amps. A thicker rod of 3/6 inch will use a higher amperage of between 140 and 225 amps. The rod container chromium, manganese, silicon, and molybdenum.

What are some uses of the 7010 welding rod

Due to its molybdenum content, it is ideal for welding molybdenum steel alloys. Also, when it comes to pipe welding the rod can be used for root and hot passes. Here are some applications of the 7010 welding rod;

  •  Used to repair various equipment including shafts, gear teeth, boilers, and oil well castings
  • Used to make root passes on pipes with API grades of x42, x46,x52 and x56
  • Used for stove piping which is welding large diameter pipes in the vertical down position
  • Used to repair rod equipment and farm tools.

7010 welding rod tips and techniques

When root welding pipes or root practice plates, use a thicker rod to do the hot pass and a thinner rod to do the hot pass. For example, you can use a 5/32 inch to do the root pass and follow it up with a 3/16 for the fill and cap pass.

Also, keep the electrode nicely jammed into the joint gap. Slow down the travel speed as well and use a higher amperage, especially for the thicker rods. For the 5/32 inch rod, you can start at 135 amps and crank it up to 145 amps if necessary.

6010 vs 7010 vs 7018 welding rod

The 6010 and 7010 are quite similar in that they are both cellulose electrodes used for vertical down welding. These two rods also have a cellulose-sodium coating.

The 7018 is different from the two as it is a low hydrogen electrode with an iron powder coating. In terms of usage, the 7010 and 6010 electrodes are both used for vertical down welding.

They are also suitable for welding steel-molybdenum alloys in high-temperature environments. Molybdenum is used to harden steel and make it less prone to stretching when exposed to high temperatures. 

The 7018 can be used for uphill welding, but its weld bead is not stronger than that produced by the 7010. 


The 7010 welding rod is a cellulose rod used mainly for fill and cap welding on pipes. It is used together with the 6010. In most industries, the 6010 is used to make the root pass and the 7010 is used to make the hot pass and fill and cap passes.
