TROY, Ohio. September 12, 2011 —Hobart Brothers announced that
it has developed a gas-shielded metal-cored wire specifically
to improve welding performance and quality on sour gas
pipeline applications. Sour gas is natural gas or any other
gas containing significant amounts of hydrogen sulfide (H2S).
Natural gas is usually considered sour if there are more than
5.7 milligrams of H2S per cubic meter of natural gas, which
is equivalent to approximately 4 ppm by volume. On the other
hand, natural gas that does not contain significant amounts of
hydrogen sulfide is called “sweet gas.”

Metalloy 71 SG wire features high deoxidizer levels that
are capable of welding through mill scale and still producing
consistent quality welds. The wire also offers excellent wetting
characteristics to ensure smooth weld beads with uniform tie-
in and help minimize weld defects and their associated rework.
Additionally, it generates a low hydrogen weld deposit — 3.3
ml per 100 g of weldment — to help mitigate cracking.

Metalloy 71 SG wire is designed for welding in flat and Metalloy 71 SG is designed to improve welding performance and
horizontal positions, and can be used in short circuit or pulse quality on sour gas pipelines, as well as various manufacturing
applications. It is also usable for welding on non-alloyed applications.
