N-7024

Specification

AWS Specification: AWS A5.1 E7024
JIS Specification: D5024
Other Specification: DN E5121RR11160

Description

N-7024 is a rutile coated high recovery manual metal arc electrode for the high speed welding of mild and medium tensile steels
Manufactured using a heavy coating containing a large proportion of iron powder giving a nominal efficiency of 160%
Has a rapid melt-off rate and is suited to high productivity applications
Exhibits excellent welding operability with little spatter and trouble free strike and re-strike characteristics
Suitable for use in the flat position for butt welds and in the gravity and horizontal-vertical positions for fillet welds
Self detaching slag

Application

Structural steel
Girders
Beams
Tanks
Vehicles

Remarks

Adjust the welding current to keep the proper slag covering because optimum welding current is subject to the welding process and the surface condition of steel plate

In the case of horizontal fillet welding, keep the optimum speed ratio among 1.0 ? 1.5

Dry the electrodes at 70 ? 100� C for 30 ? 60 minutes before use because excessive moisture absorption causes undercut and irregular beads
