High Temperatures? No Problem for the XVC-O Weld Camera

Posted by Dean Zhao on Friday, November 08, 2013 @ 02:49 PM

Some specialized welding processes, such as Orbital Welding processes used at nuclear power generation facilities, are done in a high-temperature environment where the base metal is often preheated to over 260° C (500° F) to ensure proper welding occurs. To be able to properly monitor the process, a Weld Camera should be used, but it has to be able to operate in the high-temperature environment.

To make sure the Xiris XVC-O Weld Camera could operate under such conditions, we put it to the test in our laboratory.

We placed the XVC-O in a high-temperature cooling kit that included a thermal blanket and air cooling, and then we subjected it to a temperature of 278° C (532° F) for four hours in a heat chamber.

 

The Xiris Weld Camera with High Dynamic Range imaging is placed in a heat chamber for testing.

Cooking the XVC-O!

 

By applying cooling air into the cooling unit, we kept the interior of the XVC-O within a comfortable operating temperature of less than 40°C (104°F) through the entire four hours using only 0.275 m3/minute (roughly 9 CFM) of airflow —more air could have kept the camera even cooler.

 

The Xiris XVC-O stays cool in extreme heat using a cooling kit.

Our Cooling Kit kept the XVC-O at below 40° C.

 

The result of our experiment proves what we expected— that an XVC-O equipped with such a cooling kit will be able to function effectively over long periods of time, even in the excessively high temperatures of nuclear power generation facilities.

This is good news for the nuclear power industry because the harsh environment inside nuclear facilities calls for Weld Cameras to be used to monitor the welding process, so that operators can monitor welds from a safe, remote location, away from higher levels of radiation. 

If the weld camera has High Dynamic Range imaging capability (such as the XVC-O), operators can clearly view in real time the entire visual range of the weld scene, including both the super-bright arc and the much darker background. This enhanced weld visibility can facilitate substantial productivity and quality assurance improvements to the welding process.

The high-temperature testing we did in preparation for the XVC-O’s use in nuclear facilities is just one example of Xiris’s commitment to continually testing our products to ensure they work in the most extreme of welding conditions.
