Copper is a versatile and malleable metal used in many industries, from electrical wiring to arts and crafts. Welding copper can be a bit tricky due to its high thermal conductivity and the possibility of gas formation. However, by following these 13 steps, you’ll become a skilled copper welder in no time.

1. Gather necessary tools and materials: You will need a TIG welder with a high-frequency start, shielding gas (100% argon), filler rods, clamps, gloves, safety glasses, helmet, and a well-ventilated workspace.

2. Choose appropriate filler rod: Use a filler rod made of deoxidized copper for best results. This helps prevent oxidation during the welding process.

3. Clean the copper: Thoroughly clean both pieces of copper by removing any dirt, oil, or oxides with a nylon brush or acetone-soaked cloth.

4. Deburr edges: Smooth down sharp edges at the joints you want to weld using a deburring tool or fine-grit sandpaper.

5. Align and clamp the pieces: Position the copper pieces on your workbench as desired for welding and secure them in place with clamps.

6. Set up TIG welder: Consult your welder’s manual for proper settings based on the thickness of your copper material while ensuring that you’re using a pure tungsten electrode.

7. Prepare shielding gas: Connect your shielding gas bottle to the TIG torch and set your flow rate between 15-20 cubic feet per hour (CFH).

8. Adjust amperage setting: For every thousandth inch (.001”) of material thickness, set your amperage between 30-70 amps (e.g., .125” thickness requires 125-175 amps).

9. Wear protective gear: Put on gloves, safety glasses, and welding helmet to protect yourself during the welding process.

10. Strike an arc: Position the torch close to the joint area and strike an arc using a high-frequency start. The arc should be stable and consistent.

11. Weld the copper: Start moving the torch slowly along the joint, ensuring an even and consistent weld puddle. A gentle brushing movement will help maintain an ideal heat balance.

12. Fill in gaps: If any gaps appear during welding, use your filler rod to add more material and fill in those areas.

13. Allow welded piece to cool: Once finished, switch off your TIG welder and allow the welded copper piece to cool down naturally before handling or examining it for defects.

By following these 13 steps, you’re well on your way to mastering the intricate art of copper welding. With practice and patience, you’ll be able to create strong, aesthetically pleasing welds on a variety of copper projects.
