R106Fe type low alloy heat resistant steel hand electrode, also known as AWS standard E7018-A1 type heat resistant steel hand electrode is iron powder low hydrogen type drug skin, containing Mo0.5% pearlite heat resistant steel electrode, melting efficiency is about 110%. Usually DC reverse connection, but can be AC welding, short arc operation, can carry out full position welding. Before welding, the electrode must be baked at 350℃ for 1 hour and used as needed. Before welding, the weldment should be cleaned of rust, oil, water and other impurities.
