Final answer:
Aluminum and steel differ in terms of corrosion resistance, melting point, and thermal conductivity during welding.
Explanation:
Welding with aluminum differs from welding with steel in several ways:
- Aluminum forms a protective oxide layer when exposed to air, making it less prone to rust and corrosion compared to steel.
- Aluminum has a lower melting point than steel, requiring different welding techniques and equipment.
- Aluminum is more thermally conductive than steel, leading to faster heat dissipation during welding.
