Product Description

Agglomerated flux SJ501
AWS F6A2-EL12
EQUIV F7A0-EM12
DIN BAR188AC10KM

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.

Applications:
Match with suitable welding wires(EL12, EM12, H08MnMoA), It may weld many kinds of carbon and low alloy structure steel, such as ship building, pressure vessels and boilers etc.


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.
