Photographic Guides
Like all electrical connections, a visual inspection is
no guarantee of performance. Crimped or bolted
connections cannot be inspected visually, but
CADWELD
® connections can be visually inspected
and provide an indication of the quality of the
weld. Visual inspection is recommended as a
practical minimum.
Use the photographs on the following pages as a
guide to visual inspection. CADWELD connections
are normally rated as good, acceptable or reject.
A good connection is a normal weld with only
minor surface imperfections.
An acceptable connection is a less than normal
weld, but a good performing weld. Imperfections
indicate that 1) a new mold is required, 2) a change
in procedure is necessary, or 3) the proper mold
conductor and/or welding material should be used.
A reject connection shows inadequate fill or
an extra high riser due to 1) use of incorrect
procedure, 2) use of incorrect equipment and/or
equipment worn beyond its useful life, or 3) use of
incorrect material.
