Que hàn cường độ cao NIHONWELD N-7016

I. APPLICATIONS:

Welding of mild steel, medium carbon steel and 50 kgf/mm² high tensile steels for ship, bridges, heavy structures, pressure vessels, machinery and others.

II. DESCRIPTIONS:

N-7016 is a low hydrogen type electrode with excellent crack resistance, mechanical properties and X-ray soundness. The Welding in all position can be easily done with the good usabilities of stable arc, slag removal and bead appearance.

·         Excellent performance in all positions (except vertical down) due to its stable & smooth arc even on AC welding machine

·         Easy slag removal and good bead appearance.

·         Few spatterings.

·         Excellent crack resistance, mechanical properties & X-ray quality weld deposits.

·         With arc starter flux on the tip of electrode for easy initial arc ignition.

 III. NOTES ON USAGE:

·         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 prepared to prevent blowholes at the arc starting.

·         Keep the arc as short as possible.
