DESCRIPTION: 

WELDMETAL – 7018 is a basic coated, Iron powder low Hydrogen electrodes, Specially design for welding of medium-high

tensile steels with RADIOGRAPHIC quality welds metals, weld metal recovery is min. 110%. Weld metal has an excellent

ductility and notch toughness down to minus 30°C which is the greater and the special characteristic of weld metal-7018

electrodes, Typical hydrogen content is 5ml/100 gms of weld metal deposit cause to save the cracked from weld metal &

provide the good strength of the job.

 

APPLICATIONS: 

WELDMETAL- 7018, is best to weld the following as : Storage Tank, Blast furnace Shells, Pressure Vessels, Railway Wagons,

Penstocks pipelines, Boilers, Dynamic loading structures, harden able low alloy steel, equipment subjected to High Stress

and Dynamic Loading, equipment requires having impact at minus -45°C, thick & heavy plates of carbon & High Tensile steels.
