Lasimm Machine

 

The Large Additive Subtractive Integrated Modular Machine (LASIMM) project is now live and ready to build large 3D printed metal structures for construction. The machine is the first of its kind and is predicted to keep Europe's manufacturing industry as a leading competitor in the global market. The project highlights a milling robot – the first for additive manufacturing of aluminum and steel - to integrate seamlessly additive, subtractive, metrology and cold work applications into a single machine. 

LASIMM will enable the creation of mixed-material structures by using similar and incompatible substances along with  software to generate tool paths and machine sequences. The machine will ensure the component's structural integrity by allowing in-process, non-destructive testing and restoration of defects. 

Xiris partnered with Cranfield University, a defining member of the project, and delivered the XVC-1000 HDR Weld Camera as an inspection solution for LASIMM. We are honoured to contribute to this project and are excited to see the results of the project and the impact LASIMM will have on Europe's additive manufacturing industry.

The South Dakota School of Mines & Technology Relies on XVC 1000

Posted by Catherine Cline on Tuesday, April 12, 2016 @ 01:00 AM

Recently, Xiris had the pleasure of working with the Additive Manufacturing Laboratory (AML) team at the South Dakota School of Mines & Technology.   AML has been using the XVC 1000 camera to assist with its metal additive manufacturing automation process.  AML has used CCD cameras in the past, but according to Joshua Hammell, Research Scientist and AML Lab Manager, “the high dynamic range of the XVC-1000, provides orders of magnitude more information about the process, while removing the need for different optical filters during cold alignment and high temperature processing. This is a major advantage for process automation.” 

The XVC 1000 has been an essential tool for machine and process development, saving the team at AML a great deal of time and money.  The initial plan for the camera was for laboratory use only; however, AML has since decided that the cameras will be integrated into all of its metal additive manufacturing systems for process monitoring during production. 

Details of the current AML process are very confidential but AML has granted us permission to show an older process development video taken with the XVC 1000…

Bring Welding Education into the 21st Century with Weld Cameras!

Posted by Cameron Serles on Tuesday, August 05, 2014 @ 04:28 PM

One of the biggest problems instructors face when teaching welding students is demonstrating proper welding techniques in a way that all students can see them.  The traditional solution has been to repeat the demonstration over and over to small groups of students so that everyone can see and understand what is going on.  This causes instructors to battle time pressure to perform all the required welding demonstrations within the limited number of class hours available.  Another problem with this solution is that students may not all see the same issues, or get the same level of explanation.  But that was with the traditional solution, and the 21st century brings better solutions for such issues.

Today, progressive welding educators do not need to face these century old issues.  By implementing a weld camera that can view the huge range of brightness present in an open arc welding environment (including the weld arc and its darker surrounding background), welding schools and colleges can provide their students with a clear view of the weld process. This allows instructors to explain and demonstrate what is really happening with the weld arc, as well as its immediate environment (such as the weld seam, weld pool, shielding gas, wire feed and other inputs).  Furthermore, this allows students to receive the same demonstrations and explanations of one weld, and provides a more consistent teaching method for welding educators.

By using a camera that can generate a clear view of the weld parameters, educators can get better use of their facilities as they can train more students in less time. They can also eliminate space restrictions of larger classes, enhance students’ basic understanding of the welding process, and enhance their school’s reputation amongst prospective students with the addition of small but evolutionary camera.

For the students, the implementation of a welding camera can create a more enjoyable learning experience, requiring less time to gain the skills needed, and raise the perception of welding as an advanced trade and skill. 

By using a weld camera, educators can create new ways to deliver education, such as recording videos of good quality welds for off-line review by students. These videos can also be used for marking or testing purposes, and the implementation of 21st century learning technique: online learning of welding processes!

How to Get the Best View of an Open Arc Weld

Posted by Cameron Serles on Thursday, July 17, 2014 @ 06:00 PM

Attaining a good image of a weld and the surrounding background has been a struggle ever since video cameras for welding became available.  The problem has always been the range of brightness that occurs during welding: the ratio between the maximum and minimum light intensity is usually too great for a standard camera to measure properly.  Standard cameras on the market today can typically measure about 1,000 levels of brightness between the maximum and minimum light levels in an image.  However, in a typical open arc welding environment, there is a brightness range that can exceed 10,000,000 levels of brightness between the brightest portion of the welding arc, and the darker areas surrounding the weld.  Using a standard camera to image such a weld will create an image similar to the image below on the left, where the camera sensor will image the scene up to a point and then saturate when it gets too bright. This causes the bright areas of the image to appear as a white blur.

 

To solve this problem, Xiris Automation has developed the XVC-O View Camera that uses advanced electronics with logarithmic sensitivity to be able to see more than 10,000,000 levels of brightness in an image.  As a result, more image detail is visible than ever seen before. The detail of the weld arc, the shielding gas, weld pool, torch tip, and weld seam can all clearly be seen.  The image below on the right is an image taken from the XVC-O camera of an open arc welding process. The weld arc is no longer saturated and is clearly visible as is the detail of the background, providing better quality information for the weld operator.

With the ability to see more detail of the weld arc and the surrounding environment, welding technicians are able to use the XVC-O to better control their welding processes through better quality assurance and process feedback.

Post-Secondary Schools Increase Trade Resources and Improve Student Experience

Posted by Cornelius Sawatzky on Wednesday, July 02, 2014 @ 04:16 PM

Technical trade schools and welding education programs are not new to post-secondary institutions, but as organizations see an increase in admissions, there is also a noticable increase in demand for equipment. This is not only to appease the quantity of new students, but also to ensure safety and efficiency in the curriculums. The most appealing program to a student will have experienced and knowledgeable professors, interesting and extensive material, as well as modern equipment. However, even with all of these tools there are still some major factors that all of these institutions face:

  • The booths to demonstrate and instruct welding are too small for more than just a few students at a time
  • The instruction area has inadequate space for the number of students registered in the program
  • The welding consumables budget is insufficient and will not cover the cost for new equipment

When instructing such a unique trade, it is important that students not only understand what is being taught, but can see the demonstration. Being able to see and understand what is occurring with a weld tip and arc, as well as the environment around it (weld seam, weld pool, shielding gas, and wire feed) are all essential elements to understanding the welding process. Without a grasp on these elements and factors, there is little that can be retained by the student. This is all based on a visual demonstration that can be hard to provide in many welding institution settings.

As technology and equipment advance, the ability to record lessons and welds adds an immense benefit to both students and instructors. Students can learn more outside of the classroom, as well as retain and digest all of the important elements of the lesson using video playback. This can be provided through the addition of weld cameras.

Not any camera can be placed in such a hostile environment, and expected to function normally. Therefore, more research and development has been contributed to constructing a small, clear, and functional camera that can withstand this environment, and provide the best image quality. Xiris Automation Inc. has created such a camera, called the XVC-O (Xiris View Camera for Open Arc Welding). This allows video recording, clear images, storing/saving capabilities, as well as better classroom visuals for welding programs. This live weld feed can be attached to a simple monitor (as demonstrated above), or even a full size projector, and still provide a clear, comprehensive view of all elements. Xiris has also developed a version for submerged arc welding.

Local colleges, such as Conestoga College, have added this kind of technology to their budding trades programs. As the Government of Canada announced this May, they are investing $2.3 million over the next five years towards Conestoga College’s new Centre for Smart Manufacturing establishment. Already using the XVC-O, these improvements have allowed Conestoga to become an extremely competitive College in the area, and one of the most competitive for the welding trade school industry. Other institutions, such as NAIT (Northern Alberta Institute of Technology) have also added systems to their curriculum and have noticed great improvements. NAIT’s Chair of Welding Programs, Chris Manning says “by displaying the captured welding video on a remote screen, the instructors can vastly improve the learning experience of their students, with improved learning success, which is always the instructor’s goal”.
