Weld Revolution Uses the Xiris Color Weld Camera

Last week Xiris Automation was given the opportunity to work with the team at Weld Revolution and record some footage with the new XVC-1100 color camera.   

Weld Revolution’s SpinArc® welding torches utilize a high speed rotating weld arc to enable the welding of all metals in any position using either metal-cored or solid wires in spray transfer or pulse modes.  

The unique stirring action delivers clean robust welds and is extremely effective for narrow groove welding.  The above video, captured with the XVC-1100 color weld camera, shows how smooth and consistent the SpinArc® process welds as it travels down a 3” deep groove and as a result, the weld bead typically requires little or no beveling.

Even with the incredible brightness of the arc and the outer walls of the narrow groove, the XVC-1100 colour camera was able to automatically adjust and deliver an excellent picture with detail of the melt pool, side wall tie-in, alignment, heat effected zone, and even wire spin.

Xiris Weld Cameras in Long-Distance Pipeline Manufacturing

Posted by Dean Zhao on Tuesday, May 10, 2016 @ 02:30 AM

The manufacturing of long-distance pipelines for the oil and gas industry uses automated orbital welding systems to join together each piece of pipe to the main pipeline.  During the welding process, the operator needs to monitor the wire-feed position and the molten puddle in real-time to ensure weld quality and inspect for the presence of weld defects as the orbital welding system is moving.  Since the weld torch rotates 360° around the pipe and the operator has to follow the weld torch while wearing a weld helmet, monitoring the weld is both labor intensive and potentially hazardous.  As a result, it is sometimes difficult for the operator to properly focus on the welding process.

Using Xiris’ high resolution and high dynamic range weld camera, operators can sit beside the automated orbital welding system while remotely monitoring the weld arc, molten puddle, feed wire, and other important information that relates to the quality of the weld.  The Xiris Weld camera includes software with crosshair graphics which can help the operator to align the weld process within the groove between the two pipes.

The Xiris weld camera can greatly reduce the physical strain of weld monitoring while improving the safety of the work environment, allowing operators to comfortably focus on the quality of the welding.  The result is that the Xiris weld camera can help improve the overall welding process in pipeline manufacturing and reduce the re-work required.

Detecting Slag Build-up on Ferrite Casings in Pipe Mills

Posted by Cornelius Sawatzky on Tuesday, April 26, 2016 @ 02:00 AM

 A major challenge in producing good quality pipe on a welded Pipe Mill is the build-up of slag on the ferrite bundle used inside the pipe. Slag is a mixture of metal oxides and silicon dioxide that is a byproduct of separating the steel from its raw ore.  Ferrite bundles are typically placed inside the pipe to help concentrate the electrical radiation towards the seam to be welded.  During welding, slag can drip down from the molten metal at the edges of parent material, building up deposits on the ferrite bundle casing surface inside the pipe.  The result is a potential reduction in power concentration at the weld point, which could lead to weakened pipe welds.  Known as a “Ferrite breakdown”, it needs to be identified early in the weld process in order to avoid poor welds from making their way down the line or out the door to the customer.

 One obvious solution would be to periodically stop the mill and open up the pipe and visually inspect the casing; this of course is not always a feasible or desirable solution.  A better approach to identify changes over time is by monitoring the shape of the weld bead. This can be done by operators who might visually inspect the scarf coming off the tube for signs of change and or abnormalities.  However, as slag could build up on the surface of the ferrite bundle casing which is inside the welded pipe, it is difficult for the operator to notice any slag buildup.

A better solution would be to use a laser based profile measurement system such as the Xiris WI3000.  By using a precise laser with a high speed camera, multiple images of the weld bead and its immediate area can be taken.  The shape of the weld bead can then be automatically analyzed for potential defects.

If there is slag buildup on the surface of the ferrite casing and less power makes it to the seam of the pipe, the top of the weld bead may become flatter or even concave as a result of reduced weld power concentration.  Visually it may appear to the operator as a “pasty” weld and we like to call it a “freeze line” defect.

When monitoring the weld bead using a laser profile of the weld zone complemented with some real time geometrical measurements, the operator can be alerted to the freeze-line condition defect much sooner.  As seen in the picture below taken from the screen of a WI3000, the operator is provided with a magnified view of the weld zone readily visible from afar.  In this view the weld bead is starting to flatten and if it becomes concave, the operator would be alerted before a potential faulty weld is generated.

The shape of the weld bead on an ERW pipe mill can provide much information.  In particular, if a laser based profile measurement tool is used, such as the WI3000 from Xiris, early detection of defects such as freeze line can be made.  Such defects often occur as a result of a reduction of power making its way to the weld zone resulting in incomplete heating of the weld bead. By providing early warning of such defects, operators can correct the problem before it becomes a critical failure.

If You Can’t See It, Should You Sell It?

Posted by Cameron Serles on Thursday, August 28, 2014 @ 03:06 PM

Xiris Automation specializes in “machines that can see”. We provide some of the world’s most dynamic manufacturers with the ability to detect, recognize, and interpret quality defects in their manufactured goods. As quality standards continue to rise, the expectation of quality fabricated products also increases.  Reducing scrap rates and increasing productivity, while providing consistent quality welds are high expectations with no room for compromise.

So, this raises the question: if you can’t see what you’re welding, are you confident selling it?

Today there are tools that allow metal fabricators to ensure that what they are providing their customers is at the best possible quality level.  One of the most effective tools for monitoring the weld quality is a weld camera.  A weld camera, such as the Xiris XVC-O camera, provides the ability for the welding process to be monitored remotely by an operator. This allows the operator to monitor the process and make adjustments to ensure the welding process has the best quality possible, while increasing the health and safety of their work environment.  

What the XVCO shows

The image above is an example of what the XVC-O system can provide.  As you can see, most features in the welding environment are clearly visible: the weld tip, weld pool, filler wire feed, seam alignment as well as the surrounding background.  This gives the operator enough information to make an informed decision about how to control the weld quality before problems develop.  It also allows for reduced welding process set up time, as any errors in the welding process will be detected right away by the operator, minimizing down time and scrap. The XVC-O Weld Camera provides clear detail of the welding process, allowing for consistent, high quality welded products to be fabricated.

 

Information on the XVC-O and all other Xiris products is available on our website www.xiris.com, including a library of recorded weld videos for your review.
