PA-7010-A1
AWS Specification: AWS A5.5 E7010-A1
JIS Specification: NONE
Other Specification: NONE
I. APPLICATIONS:
PHILARC PA-7010-A1 is most adapted to welding of long distance pipe lines. It is also designed for use on carbon moly piping used in high pressure, high temperature steam service, structural shape, plates or castings where the molybdenum content is approximately 0.50%. It is appropriate for welding higher strength carbon and low alloy steels having a tensile strength of 83.0 ksi. May also be used to join some dissimilar Cr-Moly steels of high alloy content to those of lower alloy content.
II. DESCRIPTIONS:
PHILARC PA-7010-A1 is a high cellulose electrode designed specifically for vertical down welding of all passes on high tensile pipe. These electrodes are characterized by a steady, forceful, concentrated arc to insure good penetration and wetting action. The slag is fast freezing, minimizing slag interference, and allows for easy control of the weld shape and size.
III. NOTES ON USAGE:
The root pass is deposited in the vertical down position. A drag technique is used and the electrode is pressed tightly into the joint. The second or hot pass should be deposited as soon as possible after the root pass. The current should be high enough to burn out any possible wagon tracks or slag. A slight weaving technique is usually employed. The filler passes are applied using a weaving technique in order to completely fill the joint. Excessive travel speed should always be avoided to lessen any chance of porosity. Pre-heat and interpass temperatures between 300ºC and 400ºF are recommended.
