N-55 GRAY

Specification
AWS Specification: AWS A5.1 E6013
JIS Specification: D4313
Other Specification: N/A
Description
  • N-55 GRAY is the most popular and welder-friendly general purpose rutile coated welding electrode
  • Easy initial arc strike (ignition and "cold" re-striking properties)
  • Easy tack welding or point by point welding
  • Ultra smooth, quiet, and stable arc
  • Low level and odorless fume
  • Easy slag removal (self-releasing in most conditions)
  • Beautiful and finely rippled bead even in fillet welding for nice finishing
  • Oustanding all position welding performance including vertical down
  • Can use "touch type" or "contact" welding giving ease and comfort to welders
  • Fine and very few spattering

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.

  • Steel structure - trusses, portal frames, tubed framework
  • Sheet and plate metal structures and containers (i.e. plating, storage tanks, hoppers, silos, bins)
  • General steel fabrication and assembly job
  • Welding of jeep, auto bodies, and vehicles
  • Welding of farm and agricultural equipment, fences, farm tools, etc.
  • Light steel frames (i.e. grills, ornamental and gate works, furniture)
  • General workshop welding and maintenance
  • In the case of vertical downward welding, manipulate the electrode keeping its tip in contact with mother plate
  • Pay attention not to exceed the range of proper currents
  • Welding with excessive current not only lowers X-ray soundness, but also causes increase in spatter, undercut, and insufficient slag covering
  • For Philippine market only
