PA-7016-G

AWS Specification: AWS A5.5 E7016G

JIS Specification : DL5016-B-1

Other Spcification: DIN E5155B(R)10

 

I. APPLICATIONS:

Welding of LPG tankers, LPG storage tanks, nuclear power plants, bridges and pipe lines in cold regions.

II. DESCRIPTIONS:

PA-7016-G is a low hydrogen type electrode for 50kg/mm² class high tensile steel and Al-killed steel used in temperature up to -45ºC

• 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 300-350ºC 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.
