The initial two numbers signify the minimum tensile strength which is determined in pounds per square.
E6011 welding rod uses.
More of a drag rod the 7018 is also referred to as a low hydrogen or low high rod in the field.
The 6011 rods are manufactured for operation under direct currents while 7018 rods can be run under direct or alternating currents.
Multiple pass welds with in the pipe welding industry are very commonplace.
Many welders choose 6011 electrodes for maintenance and repair work when a dc power source is unavailable.
The 6011 and 6013 electrodes can be used on both alternating and direct currents.
All four of the welding rods which we ve looked at are all position rods which offers great versatility.
The 6011 welding rod is engineered for everyday general welding applications.
In that sense the 6010 welding rod is slightly more specialized as it requires specific tools and a higher level of skill to use.
The flux contains almost no hydrogen and the rod produces smooth strong welds that are very ductile.
Like 6010 electrodes 6011 electrodes produce a deep penetrating arc that cuts through corroded or unclean metals.
The e6011 welding rod is suitable for welding of mild steels galvanized steels and certain low alloy steels.
The 7018 welding rod is employed for applications that call for crack resistant welds and exceptional weld quality.
Alternating current is an electrical current that changes direction of flow while direct current flows steadily in one direction.
6011 electrodes can also be used for all position welding using an alternating current ac welding power source.
For this reason these rods are used extensively in structural welding.
Almost identical in mechanical properties but they are designed to run on a c as well as dc welding current.
It is also applicable for welding large diameter pipelines with wall thickness of less than 12 5 millimeters.
The e6011 electrode is an all purpose welding rod that can be used for repair and fabrication works.
All except the 6010 can be used with ac and dc currents.
6011 rods are the cousin of 6010 welding rods.
Professional welders use 6012 electrodes in the horizontal position for its speedy high current fillet welds.
E6011 rods are made to run on all polarities but ac seems to be the sweet spot and will definitely prevent arc blow when a magnetic field sets up and causes the rod to burn unevenly and be extra aggressive.
