Product description

SJ101G is a fluoride-basic sintered flux delivering enhanced low-temperature impact toughness under high-heat-input welding. Suitable for single/tandem-wire SAW of low-alloy steels, with superior weld metal strength versus standard SJ101.

Certified Applications:

• Boilers/Ships/Bridges with H10Mn2 wire (NB/T 47018 compliant)

• X70/X80-grade Spiral/Straight Pipes with:
  • H08MnMoA (single-wire)
  • H08MnMoTiB (tandem-wire)

Process Advantages:

• Superior arc stability

• Effortless slag removal (no pitting/sticking)

• Aesthetic bead profile

• High low-temperature impact toughness

Precautions:

1. Weld surfaces must be cleaned of oil, moisture, rust, and other contaminants prior to welding.

2. Storage conditions require strict moisture-proof measures.

3. Flux must be baked at 300–400°C for 2 hours before welding.

4. Excessive flux height impairs bead appearance.

5. Periodically replenish with fresh flux to prevent poor bead surface quality caused by reused flux.
