PIPELINER 70S-G
AWS: ER70S-G All Position MIG (GMAW) Wire Electrode
Pipeliner 70S-G MIG wire electrode
is especially intended and pack-
aged for the needs of semiauto-
matic and automatic root pass pipe
welding. Delivering low hydrogen
deposits, 70S-G exhibits an extremely
fluid puddle for outstanding wash-in
at the weld toes and uniform bead
shape. Well-suited for use on
API 5L-X56 through X70 pipe.
ADVANTAGE LINCOLN
• Clean weld deposit.
• Uniform bead shape.
• Fluid puddle provides good wash-in
at the weld toes.
• Manufactured to actual lot control
and testing. Actual certificates of
conformance are available upon
request.
• Foil bag packaging guards against
moisture.
• Manufactured under a quality sys-
tem certified to ISO 9001 require-
ments.
TYPICAL APPLICATIONS
• Primarily intended for all-position
root pass welding on pipe steels
such as API 5L, 5L-X56 through
5L-X70
• Capable of consistent x-ray quality
welds.
• Typical applications include high-
yield pipe steels.
