This spanner had
a thick layer of
paint which made
the weld difficult
to detect.
Two welds in this spanner, both with lack of fusion.
Very poor weld with
considerable lack of
fusion.
Yet another poor weld
only discovered by our
x-ray.
This weld was an ‘extended’
12” spanner. Over 70%
of the weld incorporated
lack of fusion.

Here we show X Rays of welded, extended and fabricated Valve Wheel Spanners.
I thought all
Wheel Keys
were the same !!
VALVE WHEEL KEY / VALVE WHEEL SPANNER
8", 12", 18", 24", 36". All sizes SOLID FORGED
The tools are available in the following sizes:
8" (200mm), 12" (303mm), 18" (460mm),
24" (610mm), 36" (915mm).
All sizes are manufactured as solid forgings.
Some companies manufacture Valve Wheel Keys
as a fabricated unit, but this usually requires two
welds, which could produce a stress point causing
the tool to fail when in use. Also, please be aware
that some companies OFFER 18", 24" & 36" sizes
as 'EXTENDED' versions of the smaller sizes.
'EXTENDED' means there is some form of
mechanical extension, rather than a totally
'solid forged' Wheel Spanner.

and extended Wheel Keys read more here.
