Inspecting Ultraweld Welds
Inspecting welds to steel, cast iron, galvanized steel and
copper bar.
1. Make sure the surface is ground down to bright metal
with all coatings and oxide removed.
2. In most cases, you will be able to see a discoloration of
the metal surface around the weld.
3. Tap weld with a 12 to 16 oz. ball peen hammer at
90 degrees to weld and in such a way that you do not
damage the conductor or hard enough that you deform
the weld. A bad weld will pop off if not made properly.

Inspecting Ultraweld Welds
Bad Welds
Weld has too much slag in the weld that may compromise
the resistance of the connection. Sleeves not filled out
which may affect the strength of the weld. Disk not properly
placed or a leak in the mold are possible causes.
Bad weld due to under filling. Body of weld is too low, it is
lower than the top of the conductors. Sleeves are not filled
out. It could compromise the resistance. Wrong weld metal
used or there was a leak in the mold.
Bad weld due to gas in the weld. This is usually apparent by
the color of the weld which will be lighter in color, the riser
will be high with a mushroom top, and there will be pin holes
apparent in top of the riser.
