PIPELINER 70S-GAWS: 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.
