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 :
- Welding of high strength API 5L pipe steels.
- welding suitable for other high strength, medium and high carbon and low alloy steels.
- 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.
Hydrogen content of : 4ml/100g max.
the weld metal when Typical : 2.50 ml/ 100 g weld metal
measured in accordance with AWS/ANSI 4.3-86 specification.
