Customer Testimonial: Xiris Tube & Pipe Inspection Systems Transform Quality Control

Posted by Emily Blackborow on Thursday, January 24, 2019 @ 11:02 AM

Who doesn’t love an inspiring transformation story? Weld inspection systems truly are capable of transforming your quality assurance processes and one of our Spanish customers has quite the story to prove it.

Tubos de Legutiano Automoción (TLA) is a manufacturer of high-quality tubular products for the automotive market. By producing thin-walled exhaust pipes, TLA helps their customers reduce the weight of their parts, while maintaining high quality standards that are able to withstand the strict demands of the automotive industry.

TLA recently said that their most important customer, a large automotive parts supplier based in France, was both surprised and delighted to notice a sudden, significant improvement in TLA’s quality, so much so that they wanted to pay them a visit.

Once visiting TLA, the French automotive parts supplier realized that the improvement in quality was due to the introduction and implementation of the Xiris WI2000 Weld Inspection system used on their two tube lines.  By detecting defects that were previously not detectable using any other NDT test process, TLA was able to address the imperfections that were plaguing their production for years.

The management of TLA commended Xiris’ systems saying:

“Without precision tools that allow us to move forward and work under this precept, it would be difficult to be able to develop products according to the new demands. That is why the Xiris WI2000 has been the key for increasing the quality of our company, reducing set-up times, monitoring the quality of the product in real time and allowing to interact with accurate information in the production process.”

The result was that, once implemented, the WI2000 systems were able to catch defects and help perform better process monitoring to keep their tube product in control.  Consequently, fewer defects made their way to the end of the production line and shipped to their customer in France.

How to Detect Scarf Tool Wear on a Tube Mill

Posted by Cameron Serles on Thursday, December 13, 2018 @ 11:00 AM

During tube production, immediately after the tube has been welded and before any further in-line processing is done, the weld bead must be scarfed off the tube. Scarfing is the process whereby the weld bead is cut off with a knife, or scarfing tool.  Unfortunately, if the scarfing tool is not done properly, the tube may not meet end user customer specifications because of a rough surface left behind by the scarf tool.  The result can be the primary contributor to creating a leak path on a compression fitting.

Using a surface profiling tool such as the Xiris WI2000, the scarf defect measurement can be used to detect how well the scarfing tool is cutting the weld bead and indicate the amount of scarf tool wear. 

Scarf tool wear describes the gradual failure condition of a scarf cutting tool on a tube mill as a result of ongoing use.  It can occur either as flank wear in which the portion of the scarf tool in contact with the welded tube erodes over time sometimes causing a ridge to be left behind in the scarf zone; or as crater wear, in which contact with chips of weld bead erodes the rake face of the tool causing an uneven cut surface; or a cluster of weld bead material building up on the face of the tool causing it to dredge a groove in the scarf zone. These conditions are somewhat normal for tool wear, and they do not seriously degrade the use of the scarf tool until it becomes serious enough to cause a scarf tool cutting edge failure that may be a concern for a potential leak path for the tube in its final use.

The scarf defect measurement on the WI2000 looks for any significant deviations in surface height above or below the ideal scarf surface.  The Scarf Defect will detect the absolute value of the largest defect on the scarf surface.  Any significant amount of scarf tool wear could reduce the specifications and performance of the final tube, especially for some automotive applications where tight assembly requirements or a smooth, scratch free surface is required.

Scarf Defect_2017-01

The Definition of a Scarf Tool Wear: The scarf plane can be defined as the straight line drawn between the left and right scarf edges.  Any detected features above or below the scarf plane, are measured as a scarf defect.  The actual amount of wear is defined as the distance from the scarf plane measured perpendicularly to the scarf plane.

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.
