Robust Weld Cameras for High Frequency Weld Applications

Posted by Catherine Cline on Wednesday, May 03, 2017 @ 09:29 AM

Electromagnetic interference (EMI) that is generated by high frequency weld equipment can often play havoc with other welding equipment, such as cameras, by creating electromagnetic induction in the circuitry of the cameras.  Often the electrical disturbances that occur create a noisy camera image, interrupt image data acquisition or generate continuous lines running through the image. In xtreme cases, it can stop the cameras from functioning altogether.

The Xiris XVC-1000e Weld Camera

During extensive testing in the field, Xiris XVC weld cameras have proven themselves to be immune to the EMI that is generated by high frequency weld equipment.  EMI immunity has always been a problem identified by the industry when using cameras, so Xiris took this into consideration when designing the XVC camera family.  The camera is an all digital design, rather than the analog design common on most other weld cameras.  The result is that many problems resulting from outside interference are eliminated, allowing for excellent image stability and cable lengths of up to 100 m.  As part of that design, the camera housings have been extremely well shielded and grounded, eliminating any stray electrical noise.

The XVC weld cameras were extensively tested during the design/build process whereby extreme ranges of frequencies and power levels were used, including some of the harshest welding conditions, such as high power GMAW welding tests, with power approaching 1000A.  During those tests, the XVC weld camera cables were stretched parallel to welding power lines, wrapped around welding power lines and laid on/over/in grounded equipment, all without significant degradation of the camera image.

The camera has been tested to the EN 61326-1:2006 standard which includes the following tests:

  • Electrostatic discharge
  • Radiated RF Immunity
  • Electrical Fast Transients
  • Surge Withstand
  • Conducted RF Immunity
  • Magnetic Field Immunity
  • Voltage Dips
  • Short Interruption
  • Harmonic Current Emissions
  • Voltage Fluctuation and Flicker

The Xiris XVC weld camera is now widely used on manufacturing floors running in some of the most challenging welding environments, including alternating polarity GTAW, high powered GMAW and Plasma processes, providing clear images to operators as far as 100 m away from the weld head.
