APPLICATIONS:
Welding of 50 kg/mm class high tensile weather-proof steel of buildings, brid
SPECIAL FEATURES:
P-7016W is a low hydrogen type electrode for all position welding of 50kg/mm2 class high tensile weather proof steel.
- Excellent mechanical properties.
- Good notch toughness in low temperature.
- X-ray performance and mechanical usability are good.
Note on usage
- Dry the electrodes at 300-350ºC for one hour before use.
- Adopt back step method or strike the arc on a small steel plate prepared for this purpose to prevent blowholes at the arc starting.
- As excessive heat-input deteriorates impact values, weld with proper heat-input selected according to the impact values required.
