Description:
CHE425G
is a high cellulose
sodium type welding rod. It shows a very good performance in welding of all
positions, 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 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 steel core of rod.
