TOKO Submerged Arc Welding (SAW) Fluxes TOKO’s Submerged Arc Welding (SAW) Fluxes, including popular grades like SJ101, SJ301, SJ501, and others, based on their applications, compositions, and characteristics: 1. TOKO SJ101 (Agglomerated Flux) Type: Agglomerated (bonded) flux. Application: Designed for welding high-strength, low-alloy (HSLA) steels and quenched & tempered steels. Ideal for structural components requiring high impact toughness (e.g., offshore platforms, bridges, pressure vessels). Key Features: Low hydrogen content to prevent cracking in high-strength steels. Produces welds with excellent Charpy impact toughness at low temperatures (down to -40°C/-40°F). Compatible with Ni-based welding wires (e.g., AWS A5.23: EB3, EB6) for enhanced strength and ductility. Smooth slag detachment and minimal spatter. Standards: Meets AWS A5.23 specifications. 2. TOKO SJ301 (Fused Flux) Type: Fused flux. Application: Primarily used for welding carbon steels and mild steels in general fabrication. Common in shipbuilding, pipelines, and heavy machinery. Key Features: High stability with AC or DC welding currents. Produces clean, uniform welds with good bead appearance and minimal porosity. Low moisture absorption due to fused manufacturing process. Compatible with AWS ER70S-3/ER70S-6 wires. Standards: Conforms to AWS A5.17 (F7A2-EM12K). 3. TOKO SJ501 (Agglomerated Flux) Type: Agglomerated flux. Application: Tailored for low-alloy steels and high-tensile steels (e.g., ASTM A514, A517). Used in mining equipment, crane booms, and military vehicles. Key Features: Alloy compensation to maintain weld metal strength and toughness. Works with Mo- or Cr-Mo-based wires (e.g., AWS A5.23: EH14). Excellent crack resistance and adaptability to high-heat-input welding. Suitable for multi-pass welding.
