Description:
CHE425G
is a high
cellulose sodium type welding rod. It shows a very good performance in
welding of all positions and vertical down and overhead. The rod forms on
double sides by one side welding. It is suitable for welding root passes,
hot passes, filler and cover passes as well as for capping of general pipes
and similar structures. Keeping the rods in dry condition. The rods do not
be redried before welding. In welding small current is recommended and
swaying broad should be less than 2.5 times of diameter of the steel core of
rod.
