PA-7016U

AWS Specification :A5.1 E7016

JIS Specification: D4316

Other Specification: NONE

 

I. APPLICATIONS:

One side shieled metal arc welding for pipes and general butt joints of mild steel and 490 N/mm2 high tensile steel.

II. DESCRIPTIONS:

PA-7016U is a low hydrogen type covered electrode for exclusive use for one-side welding of pipes and general structures. It’s arc stability is extremely good to perform one-sde welding with relatively low currents.

III. NOTES ON USAGE:

• Dry the electrodes at 300-350 degrees C for 30-60 minutes before use

• Reverse side bead with good appearance is obtained with proper current and optimum root gap.

• Cut off the arc after setting the crater to the side wall of the groove to avoid crater cracks.

• Strike the arc on a small steel plate to prevent blowholes at the arc starting

• Keep the arc length as short as possible.
