RATNA 8045 P2 H4R (AWS A 5.5 E8045 P2 H4R)

Product Specification

Specifically designed for high strength pipe welding vertical down position.

 CLASSIFICATION  :- AWS/SFA- 5.5: E 8045 P2 H4R

 CHARACTERISTICS     : Low hydrogen type, moisture resistant electrode have specifically been designed for  the welding of hot, fill, and cap passes in high strength pipe butt joints using vertical downward progression.  This electrode is not recommended for welding with vertical upward position. These electrode not  recommended for the root  pass ( stringer bead ) on open gaps.

 APPLICATION               :

  1. Welding of high strength  API 5L pipe steels.

  2.  welding suitable for other high strength, medium and high carbon and low alloy steels.

  3. Hot tapping and Pipe repairing

  RE-DRY CONDITION      : No need of drying. The electrodes are vacuum packed hence can be  used straight on   the job.
