PA-7016-W

AWS Specification: NONE

JIS Specification: DA5016G

Other Specification: NONE

 

I. APPLICATIONS:

Welding of 50 kg/mm class high tensile weather-proof steel of buildings, bridges, and vehicles.

II. DESCRIPTIONS:

PA-7016-W 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.

     III. NOTES ON USAGE:

• Dry the electrodes at 300-350°C for 30-60 minutes 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.

1. As excessive heat-input deteriorates impact values, weld with proper heat-input selected according to the impact values required.
