Product description
CO-REL® SJ101 Sintered SAW Flux is a fluoride-basic sintered flux (basicity: 1.8) with gray-white spherical particles sized 2.0–0.28 mm (10–60 mesh). Compatible with AC/DC power sources, it operates optimally under DC+ polarity. Metallurgically neutral, it minimizes Si/Mn pickup in weld metal.
Process Advantages:
Superior arc stability
Effortless slag removal (no pitting/sticking)
Aesthetic bead profile
High low-temperature impact toughness
Specialized Performance:
90° fillet joints: Excellent slag peeling & smooth weld transition
High-current welding (≥800A) at 1.8 m/min: Gas pore resistance with ribbon-like slag detachment
Wire Compatibility & Applications:
Critical Industries:
Ship hulls
Boilers & pressure vessels
Pipelines
Supports: Multi-pass, double-sided single-pass, tandem-wire, and narrow-gap SAW

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.
