- Applications
- Welding of mild steel and 50kgf/mm² class high tensile strength weather proof steels for buildings,bridges and cars.
- Characteristics
-
- - W 7016N is an extra low hydrogen type electrode for all position welding of aluminum-killed steel and TMCP steel used at low temperature.
- - X-ray soundness and mechanical properties of weld metal are excellent.
- - Weld metal is 0.5%Ni-Ti-B type, and has better notch toughness at -60℃ and CTOD propertiesSizes Available and Recommended Currents ( AC or DC ± )at temperature down to -30℃.
- Notes on Usage
-
- - Dry the electrodes at 350~400℃(662~752℉) for 60 minutes before use.
- - Keep the arc as short as possible.
- - Pay attention not to exceed proper heat-input because excessive heat-input causes deterioration of impact values of all-weld metal.
