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.

1. for low carbon, low alloy and pipeline steel.
2. for thick wall structures of different high-tensile steels.

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 2 hours before usage.

Chemical Compositions:

Notes for welding:
1. Redry the flux for 2 hours at 300-350o C prior to be used.
2. Some rust, oil, moisture and other impurities must be cleared away from the area to be welded.

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.
