Z-2602 REPAIR AND MAINTENACE LOW ALLOY STEEL Z- 2603
WORK WELDING

Description: Description:
Double coated basic electrode for welding medium strength steels. Also suitable for Basic low-hydrogen electrode especially designed for general maintenance; welding
structures carrying dynamic loads. Owing to the double coating the arc is very stable cast steel and low-alloy steel. The welding material has medium to high tensile
and focused excellent for root pass on pipes and all positional welding. strength as well as very high impact strength at -46°C. Easy ignition and smooth
quiet arc with good penetration.
Uses:
