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 and the rods do not need to re-bake before
welding. In welding small current is recommended and swaying breadth should
be less than 2.5 times of diameter of the rod.
