ZT.SJ**1G（welding flux）
In accordance with GB/F4A*-H*8C F5A*-H*0Mn2
Equivalent to AWS F7A4
DESCRIPTION:
ZT.SJ**1G is a kind of special
agglomerated flux that have been designed used in welding lose oil
and lose gas steel tube. Alkalinity 1.8, it is grey spherical
pellet,size 2.**0.4(****5 mesh). Under alternating current and the
condition of direct current, it can be used. If welding wire joins
positive electrode, the speed of welding can reach *0M***0M,
Electric arc is stabilized, is easy to remove to weld dregs, join
position smooth. Join metal have the higher impact tenacity in low
temperature.
The flux with good fight tide performance, pellet strength,
can satisfy normal transportation store, circulates to use. Among
welding course the consumption of welding flux has less
quantity.
APPLICATIONS:
In combination with
H*8C,H*8MnA,H*0Mn2,h*8MnMoA,H*8Mn2MoA wires, It is suitable for
welding various pipeline steel material, such as
X*2，X*0，X*5,X*0,also be used in multilayer welding ,
two-sided only road welding, welding electrodes welding, narrow gap
bury arc welding voluntarily.
