N-7016

Specification

AWS Specification: AWS A5.1 E7016
JIS Specification: D5016
Other Specification: DIN E5154B(R)10

Description

N-7016 is a low hydrogen type electrode with excellent crack resistance, mechanical properties, and X-ray soundness
Easy slag removal and good bead appearance
Few spatterings
Stable and smooth arc even on AC welding
Easy initial arc ignition due to arc starter flux on the electrode tip

Application

Welding of mild steel, medium carbon steel, and 50 kgf/mm² high tensile strength steels
Ships
Bridges
Heavy structures
Pressure vessels
Machinery

Remarks

Dry the electrodes at 300 - 350�C for 30-60 minutes before use

Take the backstep method or strike the arc on a small steel plate to prevent blowholes at the arc starting

Keep the arc as short as possible
