AWS E8018-C1 H4

Description

Designed for applications of 2% nickel deposits, and the welding of nickel bearing steels for low temperature applications where toughness of the weld metal is important.

Applications

Welding Positions:

Single and multiple pass, DCEP, AC

• Shipbuilding

• Piping

• Storage tanks

Category

Low Alloy Electrodes

Industries

Shipbuilding, Piping, Tanks used in the storage of gases.

FEATURES

Excellent arc characteristics
L ow spatter level
Quick and easy slag removal
Low moisture reabsorption
Low smoke level
L 0W hydrogen, less than 4 mI/100 g

BENEFITS

Stable, easy to control arc
Improves weld bead appearance, higher deposition
Reduces clean-up time

TYPE OF CURRENT

Direct Current Electrode Positive (DCEP) or AC

RECOMMENDED WELDING TECHNIQUES

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 (220°F to 350°F) until used.
