OK Flux 10.45 is a fused, lowbasicity
flux for submerged arc
welding. It is for very high
welding speeds, exceeding
300cm/min, with small
diameter wires on thin plates.
The flux grains do not pick up
any moisture due to the
manufacturing process used.
The flux alloys some Mn to the
weld metal. The application
areas include butt, fillet and
overlap welds. It can be used
with single or multi-wire
procedures (twin-arc) and
works equally well on DC or
AC current.

OK Flux 10.45 is applied in the
production of lamp posts e.g.
on 4mm thick plates with a wire
diameter of 1.6mm and a
welding speed of 300cm/min.
Other applications are for high
speed welding of hot water
tanks and membrane wall
panels.
