Gee Limited

CHARACTERISTICS

A medium-heavy-coated, rutile-type electrode, depositing hardening type weld-metal of approximately 350 Brinell hardness. The weld metal is machinable with Carbide tools.  A buffer layer of GEECON PURPLE is recommended on Carbon steels and low-alloy steels.

TYPICAL APPLICATION

HARDNESS ON 3-LAYER DEPOSIT:360-470 Brinall

Weld Metal Analysis (Range) % :

Identification :

GEECON PURPLE, E7016 

Classification :

AWS/SFA 5.1: E7016    IS: 814 EB5224H3X    

Approved By : BIS

Charecteristics :

An extruded, heavy coated, hydrogen - controlled electrode. Weld able in all positions except vertical down.  Welding technique including arc striking/restricting calls for practical experience for best result.  The bead appearance is fine with uniform ripples and the slag is compact, thick and easily detachable

Typical Application :

For radiographic quality welding of highly stressed joints in steel structures, heavy-duty boilers and pressure vessels, railway wagons, coaches and trailers etc.  Also for maintenance welding/surfacing of cast steel/fine grained/heat treated steel and wrought steel. Excellent for welding of higher carbon and higher sulphur steel which are susceptible to hydrogen induced cracking.  Recommended for welding steels of unknown composition.

GRICON GREEN NC (NACE GRADE) 

Classification :

AWS/SFA 5.1 E7018-1, DIN 8529   ESY 4276MU8   DIN EN 499   E426B42H5    BS639-86    E5143B (24H)   IS 814: EB 5626 H3 JX 

Approved By : EIL-BPCL, CPCL

Charecteristics :

A basic coated, hydrogen controlled electrode deposits tough and crack free weld metal in butt and fillet joints.  The weld metal has very low diffusible hydrogen content and is resistant to ageing.  The electrode has an extremely stable arc, which enables it to be manipulated in the most difficult positions `without any risk of arc extinction due to freezing.  The deposited welds meet X-ray quality requirements.

Typical Application :

- For welding structural steels where resistance to brittle fracture is required under adverse operating conditions.

- Off-shore production platforms.

- Fabrication pressure vessels, nuclear containment vessels

- ASTM A106 Grades A, B, C

- ASTM A516 Grades 60,70

- Bridges, Pipelines, Heavy Machinery, Tanks, Penstocks, etc.
