All-State®
No. 16* Electrode
for Welding Nickel-Copper Alloys DC
Reverse Polarity (Electrode +) All Position General
Characteristics An
electrode designed to be used on critical applications. All-State®
No. 16 yields sound, porosity free deposits with
a minimum of spatter loss. The slag gives a full cover to the weld, yet is easilyremoved.
A smooth, stable arc
is typical of this electrode, even in out-of-position welding.
Typical Applications
To weld Monel* 400 or Monel* 404 to
themselves or each other. Excellent for overlay applications on steel. Will
also join other Monel alloys, carbon
steel, low alloy steel, copper and copper-nickel alloys.

Class ENiCu-7 Procedures
Clean base metal. Nickel and nickel
alloys will become brittle when welded if any sulphur or lead is absorbed
into the weld deposit. These impurities
are commonly found in lubricants, dirts, grease, oil, paint and other
processing residues. Preheating is
not recommended unless the metal drops below 32°F (0°C). A short arc
must be maintained.
Stringer beads or weave beads not more than three times the diameter of the electrode
will minimize
heat input. Remove all slag and clean thoroughly after each pass.
