Descripción
Características:
LKE-7010-A1 is a high cellulose type electrode for DC(+) welding . The welding can be done in all positions with good crack resistance, deep penetration, stable arc, and good performance.
Aplicaciones:
It is especially suitable for welding of the pipes, high pressure pipes, oil tanks, and boilers due to its good X-ray soundness.
Notas sobre el uso:
1.Dry the electrodes at 70-100°C for 30-60 minutes before use.
2.Pre-heat the work piece at 100-200°C and PWHT at 620-680°C
