Product Description

Specification: EN760 SA AR 1 88 AC H5
             AWS A5.17 F7A0-EL12 F7A2-EM12K

Application:
With suitable welding wires(H08MnA. H08MnMoA. H10Mn2), it can welding common structural steel, boiler steel, pipeline steel, etc.
The flux can be used for multiple fast welding, and can be suitable for single-sided welding, especially suitable for pressure vessel, such as oil and gas pipes, tanks and cylinders of automatic submerged arc welding.

Description:
     Agglomerated flux SJ501 is a kind of acid aluminum-titanium type sintered flux, the basicity index is
about 0.8. It is shaped as black, round grains and its grain size is 2.0-0.28mm (10-60Mesh). It can be
used with either AC or DC. The welding wire is connected to the positive electrode when used with DC.
It has stable combustion, good slag detachability and good appearance of weld. It has a thick skin to
a small quality of rust and high temperature oxidation film on account of strong the capability of resist
pore.
      As a peculiar production technique is adopted, the flux possesses better moisture resistance and good strength of grains,
which may satisfy the requirements for regular transportation, storage and recycling use in welding.
The flux has less specific gravity when it is bulk packed. And it is consumed less during the welding.

Cautions:
1.The oil contamination, moisture, iron rust and other foreign substances must be removed from the
welding joint.
2. It is better to weld under direct current.
3. Welding flux must be baked under 300-350°C for more than 2hours before usage.
