Unionmelt 231 is an active, bonded flux designed for fillet and butt welding of carbon steel plate.

This flux will produce horizontal fillets up to 3/8" (9.5 mm) leg size without undercut or rollover.
The slag peeling is excellent.

Unionmelt 231 can be used for multipass welding, but because Mn and Si buildup is possible, welding voltage should be kept to a minimum and plate thickness should be limited to 1" (25 mm).
Unionmelt 231 is suitable for DC single and parallel wire welding at currents up to 1000 A.
It is used for welding rail cars, water heater tanks, ship plates, and structural steel.
