EN ISO 14174: S A AR 1 88 AC

Description

Agglomerated active type flux primarily used for single and double pass fillet welds. Excellent resistance to rust, mill scale excellent wetting of fillet weld toes and excellent slag removal.

Applications

Welding Positions:

Submerged arc welding applications

• Joining carbon steels up to 25 mm (1” thick)

• Single and two-pass groove welds

• High-speed fillet welds
• Thin-wall pressure vessels and tanks

• Welding over mill scale and light rust

• Thin structural steel
• Railcar

Category

Submerged Arc Flux Carbon & Low-Alloy Steel

Industries

Shipbuilding, Railcar, General plate fabrication, Heavy Equipment, Pressure Vessels

FEATURES

●Active submerged arc welding flux
●Provides excellent bead wetting action
●Provides very good slag removal
●Performs well up to 1000 amps using both DC or variable balance square-wave AC currents

BENEFITS

●Allows high speed welding, even over mill scale and light rust
●Offers a flat bead contour with good tie-in at weld toes
●Reduces clean-up time to help improve productivity
●Allows flexibility in selecting productive procedures and torch configurations (single, twin, tandem, etc.)

BASICITY INDEX

~0.8 (Boniszewski)

STORAGE

Flux should be re-dried before use. Re-dried flux must be stored at 150±25°C (300±45°F) to prevent need for further re-drying

RECYCLING

The flux recycling system must be free from moisture and oil. Slag and mill scale must be removed from therecycled flux. At least one part of new flux must be added to three parts of recycled flux.

RE-DRYING

If the flux packaging has been opened and the flux has been exposed to moist conditions, re-drying is
recommended. The flux should be re-dried at a temperature of 300-350°C (570-660°F) for a minimum
of 2 hours. Re-drying should be made a maximum of three times.
