Description:
sj101G is a special-purpose sintered flux developed especially for welding
steel pipes that are used in the project of Transporting the Natural Gas from
the West to the East. With the
alkalinity of approx 1.8,it is shaped as grey,round grains and its grain size
is 2.0б1.40 mm(14б45 meshes). It can be used with either AC. or DC. The welding
wire is connected to the posiitive electrode when used with DC. It has stable
arc combustion,good slag detachability and a good appearance of weld. The weld
metal has higher low-temperature impact toughness.
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.
Usage:
Matching with suitable welding wires (H08C,H08MnA,H10Mn2,H08MnMoA,H08Mn2MoA),it
may weld many kinds of steel pipes,such as X52,X60,X65,X70,etc.It may also be
used in multi-layer welding,double-side single-pass welding ,multiple-wire
welding and narrow-gap submerged arc welding
