NIHONWELD N-6011
NIHONWELD N-6011
AWS Specification: AWS A5.1 E6011
JIS Specification:

D4311

Other Specification:

DIN E4343C4

 I. APPLICATIONS:

  • Used primarily for welding mild steels such as ASTM A-36, A-283, A-284, A-285, A-515, A-516 and ABS Hull and Boiler Steel.

  • Welding of bridges, building, piping, ship building, pressure vessels (fired and unfired) and taks.

  • Welding for galvanized steels and for rusty or oily steel in maintenance & repair work

  • Use for root pass welding using “stovepipe” technique.

 II. DESCRIPTIONS:

  • High cellulose with iron powder for higher deposition rate and high welding speed than other ordinary E6011 electrode.

  • Can be use in both AC or DC power source.

  • Fast freezing with stable, strong & deep penetrating arc force for easy manipulation in any position welding including vertical down & overhead.

  • Thin slag covering which is easily remove.

  • High quality weld metal with high ductility and pass radiographic test.

III. NOTES ON USAGE:

  • Polarity: Unless otherwise specified use AC with N-6011. The N-6011 electrodes can be used on DC+ with a current about 10% below normal AC values. Always adjust current proper arc action and control of the weld puddle.

  • Flat: Hold a 1/8” (3.2mm) or shorter arc or touch the work lightly with the electrode tip. Move fast enough to stay ahead of the molten pool. Use currents in the middle and higher portion of the range.

  • Vertical: Use 3/16” or smaller electrodes. Vertical down drag techniques are used by pipeliners and for single pass welds on thin steel. Vertical-up is used for most technique for fillet welds or V-butt joints. Apple succeeding passes with a box of straight weave, pausing slightly at the edges to ensure proper penetration and proper wash-in. Use currents in the lower portion of the range.

  • Overhead and horizontal butt welds: use a 3/16” or smaller electrode. These welds are best made with a series of stringer beads using a technique similar to those described for first pass vertical-up welds.

  • Sheet metal edge and butt welds: Use DC-, electrode negative, and hold a 3/16” or longer arc. Move as fast as possible while maintaining good fusion. Position the work 45 degrees down hill for fastest welding. Use currents in the middle of the range.

  • Pipe Welding: The procedure used should be checked for proper electrode size and polarity for the wall thickness, strength level and chemistry of the pipe line being welded.

Typical data and Test results for mechanical properties, deposit or electrode composition and other properties were obtained from a weld produced and tested according to prescribed standards, and should not be assumed to be the expected results in a particular application or weldment. Actual results will vary depending on many factors, including, but not limited to, weld procedure, plate chemistry and temperature, weldment design and fabrication methods. Users are cautioned to confirm by qualification testing, or other appropriate means, the suitability of any welding consumable and procedure before use in the intended application.
