PA-52
AWS Specification :A5.1 E7016
JIS Specification: Z3212 D5016
Other Specification: DIN E5154B(R)10
I. APPLICATI ONS:
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:
PA-52 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 machines.
-
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.
