Description

E7018 Carbon Steel Welding Electrode

E7018 Carbon Steel Welding Electrode Introduction

Welding electrodes e7018 is a kind of carbon steel electrode with iron powder low-hydrogen
Potassium type coating. AC/DC. The deposition efficiency can be improved due to the iron powder in
The coating. It has a stable arc, fewer spatters, good slag detachability and excellent welding performance.
The deposited metal has excellent mechanical properties. All-position welding.

E7018 is a Heavy coated, hydrogen controlled, basic coated, iron powder type electrode. It is specially designed for restrained joints subjected to dynamic loading and to achieve the minimum 110% metal recovery, possess, excellent mechanical properties, weld deposits are highly ductile, crack resistant and of radiographic quality.

E7018 Carbon Steel Welding Electrode Application

Welding of low carbon steel structure, especially suitable for sheet small and short weld discontinuities
And requirements of the cosmetic welding surface is bright and clean. E7018 welding rod is used for carbon steel and low alloy steel welding, such as 16 Mn etc.
