Posted by Dean Zhao on Tuesday, May 27, 2014 @ 03:00 PM

Since signing Harbin Jinlifeng Co. Ltd as our distributor for China in January this year, Xiris has established success in selling a few Xiris XVC-O weld camera systems to Chinese customers. To support our expanding business in China, Xiris will exhibit in the 2014 Beijing Essen Welding and Cutting Fair from June 10 – 13 alongside our local partner, Harbin Jinlifeng.

The Beijing Essen Welding and Cutting Fair is one of the world’s leading welding exhibitions, it is the largest and the most influential welding trade fair held in China each year.  In 2013 the fair had almost 25,000 visitors from over 50 countries, and over 1,000 exhibitors from 28 countries.  Anticipating an even bigger show this year, Xiris expects to be very busy!

Come visit us at Booth# E1710 in Hall E1 of the show, where we will be demonstrating the XVC-O weld camera for Open Arc welding, and the XVC-S weld camera for Submerged Arc welding. Using leading-edge technology our XVC-O weld camera has an extremely high dynamic range sensor, which allows the operator to see both the weld arc, and its surrounding background simultaneously.  Equipped with an HMI console and monitor, the XVC-O allows the operator to remotely view the weld information up to 40 m away. This means the operator can monitor, and record, the weld process for online or offline viewing.  The system is enclosed in a cooled, durable housing to allow the camera to work in extremely harsh environments.

We are looking forward to the show, and hope you will stop by to see what our weld cameras can do!

See you in Beijing!

Notes from ABB Robotics Technology Days

Posted by Cornelius Sawatzky on Tuesday, March 25, 2014 @ 02:04 PM

ABB is celebrating 40 years of excellence in the robotics industry and further demonstrated their role as a leading technology provider with their successfully hosted event - ABB Robotics 2014 Technology Days at its Auburn Hills, Michigan location.

Over 80 products were showcased by countless Value Providers, ABB product managers and senior officials from around the globe who were present to provide hands on demonstrations. Technical seminars were also offered throughout the event and covered a range of application training workshops to technology specific sessions.

Weld Camera for Open Arc

Xiris participated as a Value Provider sponsor and also hosted a session on High Dynamic Range Imaging for Welding. With only standing room left, attendees were introduced to a history of Weld Camera developments and advancements made in Weld Camera technologies. High Dynamic Range Imaging is now commonly used in various open arc welding applications ranging from TIG, MIG to Plasma and Laser. Using a camera to view the weld process in real time allows the weld operator to monitor and adjust the weld process immediately while staying in a safe and comfortable environment. Applications where Weld Cameras are most beneficial in production environments were discussed and attendees had the opportunity to view sample videos of various applications.

Despite the challenging travel conditions Mother Nature had in store days leading up to the event, the show floor was busy with many visitors from various sectors of the automation industry. Customers had the opportunity to see equipment in action and meet with experts to discuss their specific applications.

We are enthused about the reception of Xiris as a camera technology provider and we were delighted to participate in an event that showcased innovative technology along with providing a forum for open networking to discuss application challenges in automation technologies.

How to Remotely View Your Weld Process

Posted by Cameron Serles on Tuesday, March 11, 2014 @ 10:06 AM

Ever since the development of automated welding, operators have needed to be able to monitor the welding process to ensure that all parameters are properly adjusted, that the welding head is properly aligned with the weld seam and work pieces, and that the weld pool, weld bead, and other features are all formed correctly. 

For this, fabricators have long relied on operators to directly view the process using welding helmets and protective screens, which contain a dark green filter to remove most of the harmful content of the radiation coming from a welding arc.

However, with recent advances in electronics, cameras such as the Xiris XVC-O Weld Camera have become equipped with High Dynamic Range imaging capability.  Such cameras can capture images from a weld process across a huge range of brightness, including the bright areas of the weld arc and the darker areas of the background areas around the weld.  With such clarity of image, operators are now able to monitor the cameras from afar rather than having to be close to the welding process.

 

There is Remote Imaging……

So, with such camera technology, how remote do the operators want to be to view their weld process?  Imagine some applications such as ship building, nuclear power plants or large pressure vessels where placing an operator near the welding process is both dangerous and difficult.  In such situations, the farther away the operator can be and still monitor the welding process, the better.

Properly designed electronics allow for a robust image to be transmitted from a camera on an automated welding cell to a display up to 40 m (132 ft) away from the camera.  That allows for the operator to be safely removed from the weld process while still being able to see what is going on.

Monitoring the Weld From Your Desk

 

….And Then There is Really, Really Remote Imaging….

Sometimes an automated welding cell has been installed in a location where all the stakeholders are not able to see it and monitor it.  Production managers, engineers and senior management may all want to occasionally monitor a critical welding process even though they are on the other side of the world!

How to do it?  Camera cable lengths have their limits!  The solution is to make the camera system IP addressable so that the video images can be visible anywhere an internet connection can be found.  Xiris has implemented IP addressability on certain models of its XVC-O Weld Cameras so that customers can view the welding process very, very remotely!

 

Conclusion

Whether you want to be a short distance away from the welding process, or on the opposite side of the world, there is a way to be able to see what is going on with your welding process as long as you use the right type of camera equipment for monitoring the welding process, such as the Xiris XVC-O Weld Camera system.

Better Images, Better Instruction, Better Welding Students!

Posted by Cameron Serles on Wednesday, February 12, 2014 @ 03:50 PM

Training a new group of welding students can have a number of challenges for even the best instructors: getting all the students around the weld head to be able to see what is going on; a limited number of hours the instructor has available for actually performing the welding; how to see all the features of the weld arc as well as the background information, and how to make sure that all students are marked fairly and objectively. 

When educating welding students, providing them with the ability to view the detail of the weld tip as well as the environment around the weld tip (such as the weld seam and weld pool) is important for them to learn all the parameters of the welding process.  To overcome the visual monitoring challenges created by the presence of a very bright light source (the weld arc), as well as dark areas in the image (the background around the weld tip), a camera with a wide dynamic range of imaging is required.  Reliable visualization of the environment around the weld tip is necessary to control and adjust the welding process found on most modern welding processes.  In addition, the ability to record video and play it back to the students can provide multiple benefits for teaching and correcting welding techniques.

They Can’t All See the Details…. 

New developments in electronics has led to the creation of a new type of camera that is able to accommodate the full range of light present at a weld head during welding, allowing welding to be taught in a way it has never been taught before!

By providing a good quality image of the weld tip and background, welding instructors and their students can remotely monitor a weld demonstration and record the results for off-line feedback.  By using a camera to view the weld demonstration, the students can verify that the tip is in position and that all the welding inputs (welding wire, shielding gas, etc.) are being properly fed.  Because the area around the weld demonstration is typically quite congested for class sizes more than a few students, using a camera mounted at the welding tip allows the students to clearly view the welding process remotely.  The video can also be replayed back, off-line in the classroom for instruction, marking or review purposes.

The Technology Behind Every Xiris System

Posted by Cameron Serles on Tuesday, January 21, 2014 @ 03:42 PM

Every machine vision system developed by Xiris is based upon an internal image processing library developed by Xiris over a 20 year period including thousands of hours of coding and testing.  The library has been built up to include a number of key algorithms to perform specific imaging tasks, and includes a number of tools created for maximum specification.

 Pattern Match Tool

Figure 1: This image demonstrates the capabilities of the Pattern match tool

The Edge Tools are used to very precisely locate single edges or edge pairs in a straight line or along an arc.  Best used for precisely gauging the distance between two edges or object location (finding one or two edges precisely to locate a corner, or feature), the software has been scientifically proven in a lab environment to be accurate to better than 1/20th of a pixel.

The Blob Tool is used to perform shape analysis of randomly oriented objects in an image with over 60 different measured features.  It can be used to determine if object meets specific criteria with individual thresholds available for each parameter to quickly select the features of interest, including: Area, Perimeter, Equivalent Diameter, Centroid, Orientation, Second Moments, Bounding Box, Circularity, Eccentricity and many others.

The Pattern Match (or Search) Tool, as shown above, is used to perform pattern matching by locating two dimensional objects in a very accurate manner (1/4 pixel or better).  The Pattern Match Tool is very useful when trying to find an object in a complex scene. Additionally, this tool can be used to determine how well an object matches its ideal, or golden part. 

Used to identify lighting variations, the Light Meter (or Histogram) Tool monitors overall intensity changes or simple part presence. Another important application of this tool is the modification of the Brightness or Contrast of the overall image.

Print Inspection uses a golden template pattern, built over a series of taught images, to compare with the image under inspection.  The Euclidean distance between each overlaid pixel is analyzed to determine if the image under inspection meets with predefined defect criteria.  During the teaching phase, the tool automatically determines appropriate inspection thresholds for each pixel.

Color Tools can be used to verify or recognize a region of color on a component by comparing the candidate color to a series of pre-taught, or known colors.  The color processing can be done inRGB (Red, Green, Blue), HLS (Hue, Luminance, Saturation), CMYK (Cyan, Magenta, Yellow, Black), XYZ or other color spaces.  These tools are often used for product identification, print image quality, feature analysis.

Symbology Tools help read or verify various types of symbols, including multi-format 1-D and two-D bar codes, as well as Optical Character Verification and Recognition.  Characters can be verified or recognized down to 24x24 pixels in size.

Other tools in our software package include Temporal Tools, which can track position over time, a number of Surface Inspection tools, which range from feature detection to defect classification, and 3D Imaging with the use of Laser Triangulation, used to extract the 3-dimensional shape of a surface

Our other Image Processing Tools are used to enhance an image for the benefit of an operator, including morphology (shape based processing such as erosion/dilation or opening/closing), and neighborhood processing using convolutions, including: Sobel, Averaging, Sharpening, Low Pass, Median, Watershed, and others.

All of these tools were created to help the operator make better decisions based upon what they are able to monitor. By using its own software imaging library in its machine vision systems, Xiris is able to provide custom algorithms to suit some very specific market requirements, achieving greater speed and performance benefits that would be otherwise unavailable were a general purpose imaging library to be used. The customizable nature of this software toolkit makes a Xiris system essential for a variety of applications.
