N-6011

Specification
AWS Specification: AWS A5.1 E6011
JIS Specification: D4311
Other Specification: DIN E4343C4
Description
  • 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 and overhead
  • Thin slag covering which is easily remove
  • High quality weld metal with high ductility and pass radiographic test

NOTE:

The information contained or otherwise referenced herein is presented only as “typical” without guarantee or warranty, and Industrial Welding Corporation expressly disclaims any liability incurred from any reliance thereon. 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.

  • 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 tanks
  • Welding of galvanized steels and rusty or oily steel in maintenance and repair work
  • Use for root pass welding using “stovepipe” technique
  • Polarity: Unless otherwise specified, use AC with N-6011
  • The N-6011 electrodes can be used on DCEP with a current about 10% below normal AC values
  • Always adjust current proper arc action and control of the weld puddle
  • Flat: Hold a 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: Vertical down drag techniques are used by pipeliners and for single pass welds on thin steel. Vertical-up is used for most fillet welds or V-butt joints. Use currents in the lower portion of the range
  • Overhead and horizontal butt welds: Use a 4.0mm diameter 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 DCEP and hold a 4.0mm 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
