Shielded arc welding, also known as stick welding, uses a flux-coated electrode to create an arc between the electrode and the workpiece. The flux coating on the electrode creates a shield of gas that protects the molten weld pool from atmospheric contamination, resulting in a cleaner and stronger weld. An example of shielded arc welding is SMAW (Shielded Metal Arc Welding), commonly used in construction and repair work.
Bare arc welding, on the other hand, uses a bare electrode without any flux coating. This type of welding relies on an external shielding gas, such as argon or CO2, to protect the weld pool from atmospheric contamination. Bare arc welding is commonly used in MIG (Metal Inert Gas) and TIG (Tungsten Inert Gas) welding processes. An example of bare arc welding is MIG welding, which is often used in automotive and manufacturing industries for its speed and versatility.

Shielded Arc Welding
- Definition: A welding process where the arc is protected from the atmosphere by a shielding gas, such as carbon dioxide, argon, or helium.
- Example: Gas metal arc welding (GMAW), also known as MIG welding, uses a shielded arc to weld ferrous and non-ferrous metals.
Bare Arc Welding
- Definition: A welding process where the arc is exposed to the atmosphere, without the use of a shielding gas.
- Example: Shielded metal arc welding (SMAW), also known as stick welding, uses a bare arc to weld ferrous metals. The flux coating on the welding rod provides a shielding gas during the welding process.
Key Differences
- Shielding Gas: Shielded arc welding uses a shielding gas to protect the weld from atmospheric contamination, while bare arc welding does not.
- Weld Quality: Shielded arc welding typically produces cleaner, more consistent welds than bare arc welding, due to the protection from the shielding gas.
- Applications: Shielded arc welding is suitable for a wide range of welding applications, including thin materials, dissimilar metals, and welding in outdoor conditions. Bare arc welding is often used for welding thick, ferrous materials in indoor environments.
