3. Why Is Argon Used in Arc Welding?

Argon, a noble gas, is inert and chemically stable. Its use in argon arc welding wire applications delivers essential advantages:

Excellent Shielding: Prevents oxidation, nitrogen and hydrogen absorption
Better Arc Stability: Produces smooth, spatter-free welds
Versatility: Suitable for aluminum, magnesium, stainless, and other reactive metals
Cleaner Weld Pool: Yields slag-free, visually appealing joints

This deepens joint integrity, increases mechanical properties, and is mandated in key codes like ISO 14343 and AWS A5.10 for aluminum wire applications.

4. The Manufacturing Process of Argon Arc Welding Wire

1. Raw Material Selection
Pure aluminum ingots and magnesium alloy (99.9%) sourced; compliant with ISO 18273/AWS standards.

2. Alloying & Melting
Induction furnace melts the batch; alloy elements are analyzed and adjusted for strict composition control.

3. Continuous Casting
The alloy is cast into rods/billets for minimal segregation and optimized grain structure.

4. Hot Rolling & Drawing
Billets are hot-rolled, then drawn into precision-sized wires (0.8–1.6mm), with CNC calibrations for consistency.

5. Surface Treatment
Anodizing & cleaning processes remove impurities, ensuring high-purity conductor surfaces.

6. Quality Inspection & Packaging
Testing per ISO/AWS (tensile, elongation, chemical); packaging is customized to prevent oxidation.

Each step meets ANSI, AWS, or ISO standards to guarantee quality and traceability.
