Detailed Manufacturing Process Flow of Carbon Steel Welding Wire

The production of high-quality carbon steel welding wire, specifically our Copper Coated Welding Wire for carbon steel, involves a meticulously controlled, multi-stage process designed to ensure superior metallurgical properties and consistent performance. This process ensures the wire meets stringent international testing standards such as ISO 9001, AWS A5.18, and JIS Z 3312.

Process Steps:

1. Raw Material Selection (Steel Rod Coil): High-purity low-carbon steel rod coils are selected as the base material. The chemical composition is rigorously tested to ensure optimal levels of carbon, manganese, silicon, and other trace elements. This foundational step is critical for achieving desired tensile strength and ductility in the final weld.
2. Surface Preparation & Descaling: The steel rod coils undergo mechanical descaling (shot blasting) and chemical cleaning (acid pickling) to remove mill scale, rust, and surface impurities. This creates a clean surface essential for subsequent drawing and coating processes, preventing defects in the final wire.
3. Primary Drawing: The descaled rod is drawn through a series of dies, gradually reducing its diameter. This cold working process refines the grain structure and increases the material's tensile strength. Proper lubrication is vital to minimize friction and heat.
4. Intermediate Annealing (Optional, based on desired properties): For certain wire types or to restore ductility after significant cold work, the wire may undergo intermediate annealing. This heat treatment process alters the microstructure, making the wire more pliable for further drawing.
5. Secondary Drawing & Final Sizing: The wire continues through additional drawing stages until it reaches its final desired diameter (e.g., 0.8mm, 1.0mm, 1.2mm). Precise die selection and control are paramount at this stage to achieve accurate sizing and a smooth surface finish.
6. Copper Coating Application: The drawn wire passes through an electrolytic copper plating bath. This process applies a uniform, thin layer of copper onto the steel surface. The copper coating serves multiple critical functions: it enhances electrical conductivity for stable arc starts, reduces contact tip wear, prevents rust and corrosion of the wire, and improves feedability through welding gun liners.
7. Lubrication and Spooling: A final layer of lubricant is applied to the copper-coated wire to ensure smooth feeding characteristics during welding. The wire is then precision-wound onto various spool sizes (e.g., 5kg, 15kg, 20kg) using automated spooling machines, ensuring tangle-free unwinding.
8. Quality Control & Testing: Throughout and after the manufacturing process, rigorous quality control checks are performed. This includes:
   
   • Chemical Analysis: Verification of raw material and finished wire composition.
   • Mechanical Testing: Tensile strength, yield strength, elongation, and impact toughness (Charpy V-notch) tests on weld metal deposited using the wire.
   • Dimensional Accuracy: Verification of wire diameter and spool winding quality.
   • Surface Quality: Inspection for defects, uniform copper coating, and rust resistance.
   • Welding Performance Tests: Actual welding trials to assess arc stability, spatter levels, bead appearance, and penetration.
9. Packaging and Dispatch: Finished spools are securely packaged, often with desiccant, to protect against moisture and physical damage during transit and storage. Each package is labeled with relevant product information and certifications.
