| Objective | To demonstrate the effect of welding on corrosion.. |
| Materials | Copper and steel plates joined by welding and exposed to 3.5% NaCl solution. |
|
|
|
| Procedure |
Steel is anodic to copper and both have equal
areas. Corrosion is
observed in the welding area because of
the difference in potentials between steel and copper. Figure
