- Applications
- Welding of aluminum-killed steel for low temperature used for LPG tankers and LPG storage tanks.
- Characteristics on Usage
-
- - W 8016G is an extra low hydrogen type electrode for all position welding of aluminum-killed steel and TMCP steel used at low temperature.
- - The weld metal contains about 1.6%Ni.
- - Notch toughness of weld metal at low temperature (-40 ~ -50℃) is stable and good.
- Notes on Usage
-
- - Pay attention not to exceed proper heat-input because excessive causes deterioration of impact values of weld metal.
- - Dry the electrodes at 350~400℃ for about one hour before use.
- - Adopt back step method or strike the arc on a small steel plate prepared for this particular purpose to prevent blowholes at the arc starting.
- - Keep the arc as short as possible.
