HE-8018-D3

This electrode specially designed for welding of medium & high tensile grade of steels such as ASTM A 302 grade-B and where high strength weld is required after prolonged stress-relief treatment.

Ease of operation in all positions.
Smooth and stable arc which is easy to strike & restrike, combined with low spatter and with due control on molten pool. .
Slag detachability with little effort. .
Finely rippled bead with regular profile. Welds of consistent X-ray quality. .
Weld metal which possesses excellent mechanical properties and displays remarkable impact resistance at sub-zero temperatures down to minus 51°C. .
A higher level of metal recovery at 100-110%..
Resistance to moisture pick-up. .

Notes on usage:

Redry the electrode at 300-350°C for one hour, cool them to 100°C and transfer them to a holding oven maintained at 50-60°C.
Minimise heat input and control interpass temperatures below 150°C to obtain optimum impact values. .
Clean the weld area free of any surface contaminations.
