描述
特点
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.
应用：
It is especially suitable for welding of the pipes, high pressure pipes, oil tanks, and boilers due to its good X-ray soundness.
使用说明：
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
