Black iron pipe can be welded to steel using a process called arc welding. This is also commonly referred to as stick welding, as the process uses an electrode stick to create an arc between the metals to fuse them together. This process is used in various applications, from construction to automotive repair. Through the use of a nickel-based electrode, you can fuse together black iron pipe and steel with the proper technique.

Things You'll Need

  • Wire brush
  • Rags
  • Bench vise or clamping system
  • Work table
  • Welding helmet
  • Welding gloves
  • Arc welder
  • Nickel-based ENiFe electrode

Clean the metals that are to be welded together. Use a wire brush and rags to remove dirt or grease from the metals.

Place the pieces together as you want them welded. Use a bench vise or clamping system to hold them securely in place during the welding process. Place them onto a work table.

Put on the welding helmet and welding gloves before you begin.

Connect the grounding clamp of the arc welder to the work table.

Turn on the welder and adjust your arc settings as necessary. Create a welding pool at the point where the two metals meet. This serves as a preliminary tack, holding together the metals.

Move the electrode around the entire seam of the metal, fusing the two pieces together. Use small, circular movements as you work your way around the seam. Continue to form a weld bead around the seam until you reach the end of the area to be welded.

Allow time for the seam to cool. Use a wire brush to remove any weld spatter and to clean the weld bead.

Remove the fused metals from the vise or clamping system when cool. Paint or finish the metals as desired.

Tips & Warnings

  • Always hold the electrode at a 15 degree angle from the surface of the metal that you are welding.
  • Always weld in a ventilated area.
  • Never attempt to weld without a welding mask or gloves.
