Corotherme is low hydrogen, iron powder type electrode designed for all conventional welding positions. The electrode coating contains carefully chosen flux ingredients to provide mechanically sound weld deposits of radiographic quality. Deposits weld metal with very low level of hydrogen, which ensures the weld metal complete freedom from hot or cold cracking. It is primarily developed for the welding of weather resistant steels. The weld metal mechanical properties afford a high degree of security against heavy stress and for welds on thick plates. The weld deposit has excellent atmospheric corrosion resistance.
1. Restrict the heat input, use short arc and stringer bead.
2. Re-dry the electrodes at 250-300°C for one hour as per our standard recommended practice.
