HPP 165

MAINTENANCE ALL-POSITION

SUPERIOR ALL-POSITION CONTROLLED-HYDROGEN ELECTRODE FOR PROBLEM STEELS

GENERAL CHARACTERISTICS

HPP165 is a high tensile strength ferritic electrode.  This high quality, all position low amperage electrode features rapid deposition.  Deposits have good ductility, are dense, crack-free and of x-ray quality.  HPP165 is excellent for steels sensitive to cracking when welded with conventional mild steel electrodes.

TYPICAL APPLICATIONS:  For "tramp" and "problem" steels high in sulphur, phosphorus or other elements added to improve the machinability of steel.  For fabrication of "H" and "I" beams, angle and channel iron, pipelines and all other steel structures.  For circular tube to plate welds and other type joints subject to stress and strain.

Procedure:

Area to be welded should be cleaned thoroughly.  Surface contamination must be removed and beveled or chamfer where required.  Maintain close arc length.  Vertical joints should be welded from bottom up, using rapid weave technique.  Do not whip.  Use drag technique to make horizontal fillet welds.  Slag is easily removed.
