NIHONWELD N-AL12
AWS Specification: E4047
JIS Specification:

NONE

Other Specification:

DIN 1732 AlSi12

I. APPLICATIONS:

N – Al 12 Si an aluminum 12% silicon stick electrode for the fabrication and repair of aluminum silicon alloys.

 II. DESCRIPTION:

N-Al 12 offers the highest strength and is particularly suited to the repair and reclamation of alloy casting defects. The special flux coating provides good arc stability and slag fluidity and ensures the removal of surface oxide during welding operation.

III. NOTES ON USAGE:

Depending upon base metal thickness and mass preheating in the range 100 -300°C will be necessary. Particular attention should be paid to the joint region which must be free from any contamination. N-Al 12 Si electrode should be preferably welded in the downhand position to avoid “burn through” and excessive spattering, the electrode should be held perpendicular to the workpiece and a short arc length maintained. Electrode diameter should be roughly equivalent to plate thickness. In order to obtain corrosion resisting joints, slag residues must be reoved by washing the joint in warm water. Since the coating of N- Al 12 Si is hygroscopic, electrodes must be stored in a dry place. Use dry electrodes only!

 TEST RESULT

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.
