3. AC Stainless Steel Welding Rods: Manufacturing & Process Flow

Raw Material Inspection → Strict chemical analysis for Fe, Cr, Ni, C content as per AWS & ISO 2560 standards.
Wire Drawing → High-precision drawing of stainless alloy core wire (e.g., SUS308L, SUS316L).
Coating Preparation → Automatic powder blending for optimal arc stability & slag removal.
Electrode Coating (Extrusion) → Applying flux coating via CNC-controlled extrusion.
Pre-baking/Drying → Removal of moisture to enhance weld quality (oven baked at 350-400°C).
Cutting & Surface Polishing → Sizing and deburring for consistent arc starting.
Quality Control (ISO/ANSI) → Mechanical, chemical, and X-ray inspection for voids, cracks, and alloy homogeneity.
Packing → Moisture-proof vacuum packaging, batch coding, shipment tracking.

Key Quality Factors:

Material Purity: <0.03% S, P for superb ductility
CNC-controlled coating thickness for consistent performance
Automated flaw detection (X-ray, ultrasonic) reducing batch defect rate below 0.08% (2023 Data)
Compliance with ISO 2560, EN 1600 for international users

Manufacturing lead-time: 7-15 days per custom batch (up to 10 tons), with full traceability and ISO certification.
