H*8A is a kind of carbon constructional steel
copper-plated submerged arc welding wire. Different welding fluxes
can be selected for it to weld the workpiece, so that the
performance of welded joints is different; and in general, for
carbon steel having low obdurability on welded joints, fused fluxes
are used for welding, and for some low alloy steel, sintered fluxes
are used for welding.
Purpose: It is widely applied to welding of carbon steel (for
example, Q**5, Q**5, etc.) and some low alloy steel (for example
*9Mn2, *6MnCu, *6Mn and *5MnTi) in industries of boilers, ships,
pressure containers, pipes, etc. The used fused fluxes: HJ**1,
HJ**3, HJ**4, etc. The used sintered fluxes: SJ**1, SJ**2, SJ**1,
SJ**2, SJ**3, SJ**2, etc.

Note: If the welding voltage and the welding current
are off the standards, the mechanical property of the fused metal
and the use effect of welding wires will be affected.
Precautions:
The diameter of welding wires should comply with the size of the
electrode nozzle, if the diameter of the electrode nozzle is too
big, poor electric conduction, bad formation of weld seams, even
arc breaking will be caused;
For those welding wires which are exposed to air and are not used
for a long time, their surfaces may have rust, oil, etc. which
affect the use of welding wires; the right way is that the surfaces
of the welding wires should be completely cleaned before they are
used; and for normal welding, those impurities such as oil, rust
and water in a welding area should be completely removed;
When the welding wires are used, the inclinations of the welding
wire and the workpiece both affect the shape and the depth of
fusion of the weld pass, if the welding wire bends forward (it is
the uphill welding), the depth of fusion is big, and if the welding
wire bends backward (it is the downhill welding), the depth of
fusion is small and the width of fusion increases;
The welding flux should be baked and melted at the temperature of
between **0 and **0℃ for 2 hours before use;
The welding line energy will directly affect the weld seam
performance, so that please pay special attention to it;
For different welding fluxes are used by users and welding pieces
and process also differ, it is recommended that before the welding
wires and the welding fluxes are used, the selected welding fluxes
and welding wires need welding process evaluation so as to better
meet users’ demands.
Moving and Storage of Welding Wires
When welding wires are moved, the welding wires should be handled
with care to avoid breaking, bumping and falling, which may cause
deformation or loosening of welding wires to affect the wire
feeding performance;
Welding wires should be kept away from water and fire and are not
high-temperature resistant, so that please pay more attention when
they are stored;
When the welding wires are stored in a warehouse, the welding wires
should be kept more than *0cm away from the wall and orderly placed
according to specifications and models in order to prevent misuse,
and the use of welding wires should observe the principle of
“first-in first-outâ€.
