I occasionally want to photograph some welding in progress. Mostly MIG, as
it has a relatively small arc. Has anyone done this? Is there a danger to
a digital camera that is set back about ten feet, but on zoom to keep away
from the dingleberries? I'm guessing that it would be a manual mode with a
high shutter speed and a small aperture.
Any help appreciated.

Ive had some success with using a lighter shade welding lanes in front of
the camera....

I'd be wary of using it without a screen the high level of UV produced
stands a chance of cooking the CCD worth checking the Digital forums for
somebody doing similar.

Please log in for more thread options The issue is mainly contrast. Start with a disposable film camera so
even if it's destroyed the loss is minimal.
The problem is that there is SO much light from the arc that you
cannot see the puddle and the base material. The size of the arc being
small is not that great advantage. If there is a gas cup around the
MIG wire, it will limit the angles from which you can see what's going
on. There will be a certain amount of smoke from MIG, FCAW or SMAW.
Commercially available welding textbooks (used at the community
college level) do have good pictures that were staged for illustrative
purposes. The weldor and photographer must cooperate in order to
produce acceptable results. My copy was $40 purchased many years ago
but it has beautiful color pictures, especially the TIG welding.
If you just want to take a picture of some bright light, that's easy.
If you would like to capture what is actually happening at the puddle
level, that's a challenge.
There is SO much light and radiation within 5-10 feet from the arc, I
would not risk a digital camera which will focus that energy. A
filter, as recommended by others, would be required. Why not consult
a commercial photographer for advice as well.
