Using High Dynamic Range Cameras for Slip-Ring Applications

Posted by Cameron Serles on Thursday, August 16, 2018 @ 12:00 PM

If you use slip rings and rotating torches in cladding, there now is a way that you can see the welding process much more clearly than ever before.

Xiris has successfully tested our XVC-1000 and XVC-1000e weld cameras on rotating welding machines using slip rings—and the cameras work perfectly!  Unlike other cameras with electrical noise interferences, the Xiris Weld Cameras are not affected by the electrical noise and interferences common with running video over a slip ring.

Even Over a Slip Ring Connection, Xiris Weld Camera Maintains a Noise Free Image

Slip rings are electromechanical devices that are designed to pass electrical signals from a rotary source (such as a weld camera mounted next to one or more torches that rotate around the inside of a part) to a stationary receiver (such as a computer which receives the video data from the cameras). They are devices that allow for the transmission of an electrical signal and power.  By employing a metal brush that rubs against a rotating metal ring, the video signal coming from the camera travels through the connection, avoiding the use of solid cables that could potentially twist indefinitely until damaged.

Weld cameras are making their way into a variety of cladding operations.  However, it is very difficult to monitor cladding on the inside of the pipe, especially when the pipe stays stationary and the torch rotates.  This can be a problem for a standard connection: as the torch rotates continuously, cables cannot withstand very many rotations before they break.  Therefore, the use of slip rings would be a natural solution.  However, slip rings typically are used for motor signals and power, applications that are a little more tolerant of electrical noise than video signals.  Typical industrial cameras haven’t worked well with slip rings because their analog signals are not resistant to electrical noise.

The problem is that cladding is typically done using a TIG welding process, which is notorious for generating lots of electrical noise that can kill standard electronics due to its high-frequency starts.

But the Xiris weld cameras don’t die or short-circuit from high-frequency welding noise, even with a slip ring.  Our cameras and the welding machine keep working together when used with a slip ring—allowing operators to remotely see high dynamic range (HDR) images of their cladding process, in real time, on a computer screen, remotely.  The Xiris weld cameras with HDR capability permit operators to see both the super-bright weld arc and its dark surrounding background, with no need to stop the process.

We’ve tested our HDR weld cameras on slip-ring applications numerous times, and the advanced electronics in the cameras have repeatedly been up to the task. We’d be glad to demonstrate on your set-up.

This is new technology, but it’s ready now to improve the efficiency of your rotating-torch cladding.

Tracking Tube Production Using the WI2000 and WI3000 systems

Xiris' WeldInspection System Helps Identify the Root Cause of Variations in Tube Production

Many applications require tube producers to identify and document their tubes by batch, date and sometimes even time stamp for trace-ability. If a tube segment fails at a sub process or worse at the end user, a detailed analysis and root cause investigation follows.

Audit Log Files from Xiris' WeldInspection System

When the original tube production date and time information is available, a helpful tool to identify anomalies is to review the audit log files generated on Xiris’ WeldInspection system.The audit log files are date and time stamped and easily accessible to look for any weld related geometries that may have deviated for a time period during the production run.

Variations may be a change in bead shape/size that can be an indicator of squeeze pressure or weld heat change. With the WeldInspection system monitoring multiple geometrical conditions such as mismatch, bead height, width and potential freeze line, much information can be gained by reviewing the log files and identifying a potential root cause. Additionally if a particular condition has been identified as the potential cause, the audit logs can be utilized to determine for how long that condition existed therefore helping reduce the volume of product that might be quarantined for further evaluation.

Xiris Presents at Pipe and Tube Houston

Posted by Leanne Sinclair on Tuesday, September 23, 2014 @ 04:23 PM

This past week, The Tube & Pipe Association (TPA) and the International Tube Association (ITA) coordinated the Pipe and Tube Houston 2014 Conference, where Xiris attended to present its WI2000p Weld Inspection System.  The WI2000p system is used to inspect welded tube and pipe immediately after the weld box for forming and weld defects with the goal of performing process control.  Xiris presented on the WI2000p and how it can detect certain defects found specifically in High Frequency and ERW welded tubing. The conference was attended by several hundred members of the tube and pipe community, as well as a variety of equipment vendors.

Xiris also demonstrated the Xiris WI2000p Post Weld Inspection System at the conference’s table top exhibits.  Using actual tube samples from a variety of customers, the WI2000p’s ability to detect a variety of tube weld and forming defects, such as bead height, bead ratio, slope angle, deflection, mismatch, roll, freeze line, scarf width, and undercut.  Detection of all these critical defects was demonstrated as to how the WI2000p can assist operators in controlling their process.  The net result is to help tube and pipe fabricators decrease scrap rates, increase productivity and improve quality of the end product.
