Description:
CHE505Mo is a high
cellulose sodium type welding rod with Mo. It shows a very good performance
in welding especially vertical down and overhead. It performs double sides
by one side welding. It is suitable for root passes, hot passes, filler and
cover passes as well as for capping 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.
