AWS A5.5, E9018-B3 H4R
ASME SFA 5.5, E9018-B3 H4R
FEATURES & APPLICATIONS |
DESCRIPTION: 1180 is an outstanding welding electrode for welding higher strength piping, castings and forgings. The coating is specially formulated to resist moisture pick-up under conditions of high heat and humidity. The electrode offers resistance to moisture reabsorption which helps prevent hydrogen cracking and aids in elimination of starting porosity. Definitely a preferred electrode with high operator appeal.
APPLICATIONS:
1180 is used in welding chrome-moly pipes and boiler work.
FEATURES:
- Excellent arc characteristics
- Low spatter level
- Quick and easy slag removal
- Low moisture reabsorption
- Low smoke level
- Low hydrogen, less than 4 ml/100g
BENEFITS:
- Stable, easy to control arc
- Improves weld bead appearance, higher deposition
- Reduce clean-up time
- Prevents starting porosity
- Welder safety and comfort
- Resistant to hydrogen-induced cracking

Recommended Welding Procedures:
General: Electrode positive, work negative (DCEP) or AC
Arc Length: Very short arc
Flat: Angle electrode 10-15° from 90°
Vertical-Up: Use weaving techniques
Vertical-Down: Not recommended
Overhead: Use slight weaving motion within the puddle
Storage: After opening, store in holding oven (250°F to 400°F) until used.
Reconditioning: If exposed to atmosphere for extended periods, reconditioned for one (1) hour at 600°F.
Welding Positions: Flat, Vertical-Up, Overhead
