AWS Specification:	E6011
JIS Specification:	D4311
Other Specification:	DIN E4343C4

Applications:

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

·        Welding of bridges, buildings, piping, ship building, pressure vessels (fired and unfired) and tanks.

·        Welding for galvanized steels and for rust or oily steel in maintenance and repair work.

·        Used for root, hot, fill and capping pass welding of pressure vessels.

 

Characteristics:

• Designed for use wit both AC and DC welding power source.
• Fast freezing with stable, strong and deep penetrating arc force for easy manipulation.
• High cellulose with iron powder for higher deposition rate and high welding speed than other ordinary E6011 electrodes.
• Thin slag covering which is easily removed.
• High quality weld metal with high ductility and pass radiographic (x-ray) test.
• Can be weld with touch type or contact welding giving the welders ease asnd comfort.

 

Notes on Usage:

(1)   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.

(2)   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.

(3)   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.

(4)   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.

(5)   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.

(6)   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.
