The problem: 
In the inspection of welds for possible flaws, such 
as cracks or discontinuities, those that are not visible 
to the naked eye must be photographed in close-up 
and the negative must then be enlarged to bring out 
the required detail. All of this involves time and 
expense and adds delay to corrective procedures. 
The solution: 
An illuminated 7-power magnifier adapted to the 
lens of a standard Polaroid Land camera. 
How it's done: 
A Polaroid camera is modified by the addition of a 
magnifying lens and light source mounted in a depth-
adjustable support bracket. The light source is dif-
fused to eliminate hot spots or reflection. Power for 
the light source is supplied by two C-size dry batteries 
contained in a pack that is mounted on the camera 
case. 
Notes: 
1. Weld flaws are first located by inspection with a 
10-power magnifying glass and then photographed 
with this device, thus providing immediate pictorial 
data for use in remedial procedures. 
2. A survey of suppliers has revealed that no such 
device is commercially available.
