Mig Wire
Copper MIG welding wire is a solid, consumable electrode used in Gas Metal Arc Welding (GMAW) or Metal Inert Gas (MIG) welding. It's a filler metal that melts and fuses with the base metal to create a weld joint. Copper MIG wire is typically used to weld copper and other compatible metals. It often comes on a coil or spool and is fed through a welding gun.
Here's a more detailed breakdown:
Key Features:
- Solid Wire: Copper MIG wire is a solid, not flux-cored, wire.
- Filler Metal: It provides the additional material needed to build up the weld bead.
- Compatible with GMAW/MIG: It's designed for use with the Gas Metal Arc Welding or Metal Inert Gas process.
- Shielding Gas: It requires an external shielding gas to protect the weld pool from contamination during the welding process.
- Various Sizes and Grades: Available in different diameters and with varying compositions to suit different applications and welding requirements.
- Corrosion Resistance: Copper itself is known for its corrosion resistance, making it a good choice for applications where the weld needs to withstand exposure to corrosive environments.
- Applications: Widely used in manufacturing, aerospace, custom fabrication, construction, automotive, shipbuilding, and other industries.
How it works:
- Wire Feed: The copper wire is fed from a spool through the MIG gun.
- Arc Formation: An electric arc is struck between the wire and the base metal.
- Melting and Fusion: The high heat from the arc melts the copper wire, and it fuses with the base metal to form a weld joint.
- Shielding Gas: The shielding gas protects the weld pool from atmospheric contaminants, ensuring a clean and strong weld.
Example Applications:
Welding copper-to-copper, Welding copper-to-steel, Welding high copper content base metals where good electrical conductivity is needed, and Fabricating deoxidized copper.
