How to Weld With a 7018 Rod

Save

Shielded metal arc welding is a type of welding that uses an electrical current to pass through an electrode and create an arc that melts both the electrode and the base metal. An all-position electrode common in arc welding is the 7018 electrode. The 7018 electrode or welding rod as they are sometimes called is a low-hydrogen all position electrode with 70,000 psi tensile strength. Tensile strength means this is the greatest stress the weld can bear without tearing apart.

Things You'll Need

  • 7018 welding electrode
  • Welding gloves
  • Welding helmet
  • Wire brush
  • Welding machine
  • Chipping hammer
  • Put on all required personal protective equipment before welding. It is important that you shield your eyes from the arc at all times, while shielding the arc from the view of others.

  • Clean the base metal that you will be welding with your wire brush and chipping hammer to make sure that it is clean. The cleaner the base metal is the more stable your arc will be. This will help you make not only a good looking weld, but it will give you better penetration.

  • Adjust the amperage on the welding machine based on the size of the electrode you are using and the type of base metal you are welding.

  • When you initiate the welding process the distance of the electrode from the material your welding (Arc Length) should be the same distance as the diameter of the electrode you’re using. The top of the electrode should lead the bottom of the electrode by five to 15 degrees in the direction of travel -- meaning that the 7018 electrode is designed so that you can drag it across the surface of the base metal that you’re welding.
