How to ARC Weld Stainless Steel

Welding is an important component of any metalwork job; the skill of welding can be highly valuable to learn because of the high cost to have repair and welding done. The cost of welding work ranges from $25-$50 an hour. Imaging doing it yourself to save money and learn a valuable trade. Welding stainless steel is becoming a highly sought-after skill with the growing use of stainless steel in products; stainless steel welding projects range from welding a cracked sink to welding a leak on a grain bin.

Difficulty: Moderate

ARC Welding Stainless Steel

1. Purchase or rent a SMAW, Shielded Metal Arc Welding or Stick Electrode welder at your hardware store or equipment rental company.

2. Plug your welder into a 220V outlet and then plug in your ground cord and welder electrode holder cord into the welder.

3. Welding stainless steel requires a special electrode. Purchase an AWS E308 stick electrode to weld stainless steel.

4. Clean the surface to be welded with a wire brush.

5. Clamp the grounding clamp cord from the welder onto the piece of steel to be welded.

6. Place an electrode into the welder electrode holder, position the electrode near where the weld will start and pull your helmet over your face.

7. Tap the electrode on the steel until it strikes an arc and begin to weave the electrode stick from side to side and always keep the arc a half a centimeter or less away from the piece of steel you are welding.

8. Allow the weld to cool for a minute, then use the welding hammer to chip off the slag from the top of the weld.

Tips & Warnings

• If you ever run out of electrode and need to weld more, remember to chip off the slag coating before continuing to weld.
• Safety First! Wear proper welding protective eye wear and work in a well ventilated area to prevent fumes and gas build-up.
