A welding shop in town by here has a Milwaukee and it's okay does for what they need to get behind mill and mixer walls to see how rusted out and I think has extensions too all in a nice case. Cameras are much better now than 2 to 5 years ago.

almost any digital you buy today will do a good job of inspection work I use a pentax optia. Above and below the water with a housing good to three hunderd feet not that I ever need to go that deep.

I didnt want to use it for inspection, i actually wanted to try it on a welding application. Thought of putting a welding lense on the camera and watching the viewer instead of a mirror. It seems we have been getting into more and more applications where this would work really well

Dont know how the fibers would take the heat and splatter. If you got it too close or a spatter got imbedded into it I would think it would be toast. Most digital ones will get sun spots burned into the sensors from the concentration os focus. Sort of like the computer screen gets when you dont have a moving screen saver. I might be all wrong but for a couple of C notes if would be worth the try
Let us know how it works. You might want to buy one from a pawn shop to test with

First off, "WELDCOME TO THE WORLD'S GREATEST WELDING FORUM" JohnKish and HAPPY NEW YEAR!!! :) :) :)

What is the welding process that you're going to use with this camera?

You are going to need to configure some sort of intense enough lighting within the restricted space where you will be depositing the weld as well in order to counteract the arc which will cause background problems in viewing even with the use of a welding lens, so you're going to have to flood the space with background light of some type for better viewing through the use of the camera. ;)

If you could give us some more specifics of the application, we might be able to offer some more suggestions which could be helpful to you.

Respectfully,
Henry

Happy New Year to You also

The welding process's we are employing are Stick, Fluxcore or Tig. We use any single process or combination that will allow us to deposit a Stainless Steel Corrosion resistant barrier internally. We also have modified several standard mig guns to perform how we need them to. Typically we are working inside a 5-6" Diameter Housing 36" Long with seal glands on the interior. Access is typically from one end only, inlet and outlet ports made of 6" 2500lb weldneck flanges are also mounted on this housing which we also use for access We have been successful using mirrors but i want to go to the next level

Since i have seen video's of welding process on the net, why not use it for real time viewing.

Thank You

Your application is used all the time for automated welding. It really doesn't matter to the camera what the source of light is as long as it has a source.
You can adjust the white balance settings to appear the same as it would behind a hood. I have a lense made for my sony that is specifically for that purpose.

The only concern with it would be using it extensively without a filter lense. Over time it would burn the camera out, but if you can look at it through a lense without burning your eyes out, so can the camera.

The picture out of this thread was taken without a lense.
