Features:

  • Easily removable deposit-free slag

  • Non interference of slag with weld metal

  • Smooth and stable welding arc

  • Excellent striking and restriking characteristics

  • Minimal spatter, easily detachable slag

  • Fine rippled and defect free joints

Specifications:

ELWItm-8018-C3 is a heavy coated low hydrogen iron powder type electrode specially designed for service temp upto minus 60°C. It operates equally well on AC as well as DC(+) in all welding positions. The weld metal is tough and ductile and contains 1% nickel. The electrode is well suited for welding nickel steels and storage tanks for liquid gases where the temp requirement is upto minus 60°C.

NOTED FEATURES:

  • Smooth and stable arc with easy striking and restriking characteristics.

  • Low spatter, easily detachable slag and fine rippled, defect free bead.

  • The weld deposit is tough, ductile and is of radio graphic quality.

  • The electrode is well suited for welding 1% nickel steels and for service temp. upto minus 60C.

USES:

ELWItm-8018-C3 can be used for welding 1% nickel steels, high tensile alloy steels, boilers, pressure vessels, pipe lines and storage tanks for liquid gases where the temp. requirement is upto minus 60‚C, steels of grades A 148, A 225, A 236, A243, A 290, A 294, A 300etc.

SPECIAL INSTRUCTIONS:

  • Electrodes should be absolutely dry before use.
  • Rebake electrodes at 350°C for one hour. Cool to 100°C and then maintain at 100°C temp before use.
  • Use smaller gauge electrode to avoid excess heat and cracking of heat affected zone(HAZ).
  • Slow and uniform cooling is recommended.
