Flux for submerged arc welding
- May 8, 2021
It’s perfect for tasks in petrochemical plants, offshore construction, transport, LNG and LEG tanks, pressure vessel, and pulp and paper industries.
The enhanced formula of the flux works, in combination with selected austenitic and nickel-based wires, performs equally well with either AC or DC+ current, and provides significantly improved slag release, increased productivity and better weld quality.
As a neutral flux, it will not contribute any alloying elements to the weld metal. When combined with nickel-based products, such as ESAB’s OK Autrod NiCrMo-4, hot cracking is significantly decreased. Its low silicon content provides good mechanical properties and weld deposits. OK Flux 10.99 achieves superior tie-in, toe angles and bead appearance on interior and exterior applications.
Welding with OK Flux 10.99 using an AC output increases productivity by up to 15 per cent with the ability to use higher wire feed speeds. It provides moisture and corrosion resistance. In addition, its high weld quality reduces scrap and its increased slag release decreases clean-up time.
OK Flux 10.99 has a grain size of 0.2 to 2.0 mm and a basicity index of 2.1, making it ideal for pressure vessel, chemical and petrochemical plant applications and other industrial environments requiring multi-run welding and unlimited plate thicknesses. It combines well with many submerged arc wires, OK Autrod 308L, 309L, 316L, 316LMn and NiCrMo-4.
OK Flux 10.99 is available in 25 kg bags. For increased moisture protection and decreased risk of packaging damage, 25 kg steel buckets are also available. There is no need to redry the flux prior to use onsite because the packaging protects the flux from any moisture absorption during transport and storage.
