Applications
Welding of general structural steels for ships, bridges, machines and pressure
vessels made of mild steel.
Characteristics
V-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.
Notes on usage
(1) Dry the electrodes at 300-350°C for 30-60 minutes before use.
(2) Take the backstep method or strike the arc on a small steel plate prepared to prevent blowholes at the arc starting.
(3) Keep the arc as short as possible.
