説明
特徴
LKE-8012-C2 is an iron powder low hydrogen electrode for the welding of low temperature service steel. The weld metal contains 3.5%Ni. Good impact value can be obtained at -73°C. The welding can be done with good X-ray soundness, high deposition rate.
アプリケーション
It is suitable for the welding LPG tanks or 3.5%Ni steel for low temperature service.
使用上の注意
1.Dry the electrodes at 300-350°C for 60 minutes before use.
2.Do not exceed the proper range of current, otherwise impact value will decrease.
3.Take the back-step method at the arc starting.
4.Keep the arc as short as possible.
