How to Weld a Steel Pipe

Welding requires safety equipment, including face and eye protection.

Welding steel pipe varies greatly depending on the style and type of steel. According to the Delta School of Trades, certain steels require special preheating and cooling to ensure cracking does not occur during welding or cool down. Most welders use TIG or MIG welding tools. Online welding resource Muggy Welds suggests using a standard hand-held propane torch for steel welding. Welding rods and solders, materials used to bond during welding, melt at differing temperatures and feature designs for a variety of steel welding jobs.

Things You'll Need

• Propane torch, hand-held
• Proper welding rod or solder for style of steel
• Welding goggles

Instructions

Weld a Steel Pipe

1. Ensure welding goggles cover your eyes during the melting process to protect them from bright light.

2. Heat the steel pipe ends to be welded.

3. Melt the welding rod into the joint of the steel pipe. Or solder the welding rod into the joint of the steel pipe using a propane torch.

4. Ensure the melted welding rod or solder joint covers the entire surface of the pipe joint.

5. Allow the welded joint and steel pipe to cool.

6. Test the strength of the joint by applying pressure to the pipe near the weld.

Tips & Warnings

• Weld with steady uniform movements. Attempt to keep weld even around entire joint.

• Welding without proper protective gear can cause serious injury.
