CEWELD  4820 AC

CEWELD 4820 AC is an AC-weldable fully core-wire alloyed electrode for fabrication and repair welding on equal or similar, corrosion and heat-resistant steels and steel-castings. The weld-deposit is on equal base-material scale-resistant and, by reason of its low nickel-content, resistant against attack of sulphourus gases at higher temperatures up to 1150 °C. When welding CEWELD 4820 AC low heat-input is required as alloys of such chemistry are sensitive to embrittlement at 600-800 °C. The interpass temperature should not exceed 300 °C.
