NSW-309MoL

Specification
AWS Specification: AWS A5.4 E309MoL-16
JIS Specification: D309MoL-16
Other Specification: N/A
Description
  • NSS-309MoL is a lime-titania type electrode for all-position welding,
  • Excellent resistance against diluted sulfuric acid
  • Weld metals provide excellent corrosion resistibility and heat resistibility in the as-welded condition
  • Can be used for welding of extra-low carbon stainless steel, which contains Mo and for under laying of mother plates which contain considerably high carbon content

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.

  • Build up welding of Cr-Mo steel or carbon steel
  • Welding of AISI 316 or AISI 316L to carbon steel
  • Clad steel side welding to AISI 316 or AISI 316L
  • Keep the arc as short as possible
  • Select appropriate welding current
  • Weaving width should be within 2.5x of electrode diameter
  • When the electrodes have absorbed moisture, dry them at 250-300C for 60-90 minutes before use
