Austarc 77
Low Hydrogen Welding Electrode
The Austarc 77 stick welding electrode is smooth running and can be used for all positional welding except vertical down. This electrode is used where the highest standards are required. Weld features include high ductility, x-ray quality and sub zero temperature impact to -50°C.
AWS A5.1: E7018-1 H8
Applications
TURBINES
REPAIR & MAINTENENCE
PRESSURE VESSELS
HEAVY GIRDERS
EARTH MOVING PLANTS
Low Spatter
Exceptionally smooth welds with minimal spatter, the Austarc 77 reduces clean up time while enhancing weld appearance.
Smooth Running
The Austarc 77 welds are exceptionally smooth with excellent wash in at the toes of the weld, providing minimum undercut.
