Type of Covering:   Lime-titania


Welding Position:   F, H, HF, OH, V


Type of Current:   DCEP or AC


                                                                  


Features & Applications


It is suitable for welding structures fabricated by similar extra-low carbon stainless steels or for dissimilar steel welding, e.g. the lining of urea synthetic tower. The crack-resisting and corrosion resistance is improved due to the molybdenum to the point in weld metal.

 Noted:  1) The rod should be baked at 300℃-350℃ for 1 hour before use. 


            2) The surfaces to be welded must be cleaned away impurities of oil contamination, rust, moisture .


            3) Smaller current and short arc are recommended in welding and weave beads no wider than 2.5 times                    of the diameter of the core rod is better.
