Description:
CHE555GX
is a high
tensile strength cellulose sodium type welding rod. Very good performance
can be obtained by all position welding, overhead and vertical down welding.
Especially suitable for fabricating huge diameter high press pipelines made
by X70 or X80 grade steels. Backing weld, filling welding and lap welding
could be operated and forming on double sides by one side welding. Keeping
the rods in dry condition. The rods do not be redried before welding. Small
current is recommended in welding and swaying broad should be less than 2.5
times of diameter of core wire of the rod.
