PA-7018-W

AWS Specification: AWS A5.5 E7018-W1

JIS Specification: NONE

Other Specification: NONE

I. APPLICATIONS:

Welding of 50 kgf/mm2 class high tensile strength weather proof steel of structures, building, vehicles and bridges.

II. DESCRIPTIONS:

PA-7018-W is an all position iron powder low hydrogen type electrode which exhibits high crack resistibility and superior notch toughness of depositing weld metal. It is suitable for welding comparatively thick plates of weather proof steel.

III. NOTES ON USAGE:

Dry the electrodes at 350-400°C for about one hour before for 30-60 minutes before use.

Adopt back step method or strike the arc on a small steel plate prepared for this particular purpose to prevent blowholes at the arc starting.

Keep the arc as short as possible

The information contained or otherwise referenced herein is presented only as “typical” without guarantee or warranty, and Industrial Welding Corporation expressly disclaims any liability incurred from any reliance thereon. Typical data and Test results for mechanical properties, deposit or electrode composition and other properties were obtained from a weld produced and tested according to prescribed standards, and should not be assumed to be the expected results in a particular application or weldment. Actual results will vary depending on many factors, including, but not limited to, weld procedure, plate chemistry and temperature, weldment design and fabrication methods. Users are cautioned to confirm by qualification testing, or other appropriate means, the suitability of any welding consumable and procedure before use in the intended application.
