IS 814 : 2004 Covered Electrodes for Manual Metal Arc Welding of Carbon and Carbon Manganese Steel - Specification

1 Scope

This standard specifies the requirements for covered carbon andcarbon manganese steel electrodes for carbon and carbon manganesesteel, including hydrogen controlled electrodes for manual metalarc welding of mild and medium tensile steels including structuralsteels, depositing weld metal having a tensile strength not morethan 610 MPa.

Electrodes designed specifically for repair welding, oftenmarketed in India as `low heat input' electrodes are not covered inthis standard.

Ilmenite type electrodes are being used fairly widely in fewother countries. There appears to be a trend to use ilmenite as aningredient of the covering in our country also. Provision for aseparate class for such electrode may be considered at a laterstage.

Note - For weld metal with tensile strength higher than 610 MPa,a reference maybe made of IS 1395.
