Using Pseudo Color to Highlight Features in Welding

Posted by Cameron Serles on Tuesday, November 12, 2019 @ 11:45 AM

Weld cameras can produce color and monochrome images. Often monochrome images are selected as they provide the best resolution for a wide variety of applications. The monochrome images generated by the camera are often further processed to make the informational detail of the weld process more useful and interesting to the observer.

Usually, a tone mapping process is applied to the weld camera images to provide an enhanced image with maximum contrast for the user, such as what is done with images from the Xiris XVC-1000 weld camera. However, sometimes an additional technique called pseudo coloring can be done on the tone mapped image to provide additional visibility of key features to the user.

 

Pseudo coloring is when each grey level (or intensity value) in a monochrome image is assigned a color. The resulting image can make the identification of certain features easier for the observer, as the perceived difference in color space for the operator is bigger than between successive grey levels alone. Details such as the leading edge of a melt pool, the boundary between a torch and weld arc, the interface between the weld arc and the melt pool, or the texture of the melt pool can all be made more visible to the operator using pseudo coloring.

Why bother with pseudo coloring? You might think that your images look just fine in black and white, right? And they probably do. However, in some welding applications, adding color to an image can make it much easier to distinguish between different objects especially when they are almost the same level of intensity such as in the images above. Try it in WeldStudio™, Xiris’ software utility for weld cameras, to see if it helps.

Using Weld Cameras to Reduce Health Risks

Posted by Robin Montgomery on Thursday, October 03, 2019 @ 11:30 AM

High Dynamic Range (HDR) weld cameras provide clear images of a welding process including detail of the weld arc as well as the darker surrounding background environment, making it easy to monitor and control precise welding processes. Not only do weld cameras enable operators to see more detail of the welding process, by allowing them to see it remotely, they can improve the health and safety of operators on the job and reduce workplace costs associated with safety.

 

Common on-the-job risks that can be eliminated by removing the operator from the immediate welding environment include:

·         electrical shock 

·         "welding eye" (direct exposure of the weld arc to the human eye)

·         contact with weld spatter

·         injuries from moving or falling objects 

·         welding fume inhalation

 

Many of these risks can cause serious damage to a weld operator. It is proven that workers exposed to welding fumes are more likely to develop lung cancer than those who are not1. Adding a weld camera eliminates the need to be close to the welding process, significantly reducing operators’ risk. Using a high dynamic range weld camera can also reduce fatigue and stress, making the job safer, more enjoyable, and more appealing to existing and prospective operators.
Introducing a weld camera will also reduce costs that are associated with health and safety, such as:

·        workers' compensation insurance rates

·        employee health insurance rates

·        costs due to lost productivity

·      possible litigation

There are many other benefits to using a weld camera, but health and safety is such an important factor that cannot be overlooked. When operators are able to view the welding process in a safe, remote location, there are a multitude of positive results.

How to Make Welding More Environmentally Friendly

Posted by Robin Montgomery on Wednesday, September 18, 2019 @ 02:05 PM

In today’s world, environmental issues are becoming more and more important in all aspect of business. Currently, “humanity uses the equivalent of 1.7 Earths to provide the resources we use and absorb our waste”1. So, we want to share how you can do your part by making your welding processes more environmentally friendly through scrap and waste reduction.

 

Implementing camera systems for inspection and monitoring can help you reduce waste in your welding processes. Camera systems give you instantaneous feedback, allowing operators to immediately adjust their process before defects or scrap is created. Our customers are often our best cheerleaders: Brian Dobben, from Flowserve, credits Xiris’ dual-camera weld monitoring system with roughly an 80-95% reduction in weld defects long-term. The monitoring feedback helps reduce the scrap from welding processes that are not in control, helping operators to weld with better precision, making better, stronger welds. The end result? Final products that last longer, with less frequent replacements in the field, contributing to less waste.

Other examples exist, such as use of cameras in the classroom. By using weld cameras at schools, weld instructors can drastically reduce the weld coupons, energy and consumable materials they use by recording some of their welding lessons using a weld camera. By recording some welding lessons, the instructor doesn’t have to waste energy and materials by continuously repeating their demonstrations.

 

Cameras for monitoring and inspection can be used in a variety of different welding applications to help operators improve their quality and therefore reduce their scrap. Every step counts towards helping the environment, so take that first step by implementing a camera system with that automated welding process.

Weld Cameras: The New Tool to Teach Welding

Posted by Robin Montgomery on Tuesday, August 20, 2019 @ 12:45 PM

Using weld cameras in a classroom has many benefits for students, instructors, and administrators by providing high dynamic range images with a clear view of the weld arc, torch tip as well as the darker surrounding features such as the weld pool and seam. Weld cameras will enhance your classroom training, making them indispensable tools for teaching welding techniques.

 

Rather than always having to crowd around the instructors, with weld cameras, students are able to clearly see all features of the weld process, providing a better weld instruction experience, without the instructor having to restart or repeat the welding process should the student have missed some portion of the instruction.

 

“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 instructors’ goal”. – Chris Manning, Chair of Welding Programs at Northern Alberta Institute of Technology (NAIT)

 

Not only do welding instructors achieve their goal of improving the learning success, they also don’t have to worry about classroom space and students’ proximity to weld demos.

 

Having each lesson recorded also gives students the ability to repeatedly view and learn from those demos, and enables instructors to keep an on-going source of recorded material to avoid constantly recreating lessons.

 

Administrators experience benefits from the use of weld cameras in classrooms as well. This technology eliminates space constraints in weld training booths and allows instructors to teach more students, faster. Weld cameras can also enhance the program’s reputation, which attracts even more students to the school.

Ground-Breaking Technology + Dedicated Customer Service = Great Value

Posted by Cameron Serles on Thursday, June 13, 2019 @ 01:00 PM


Welding Process Image Once we’ve demonstrated to potential customers how a Xiris weld camera can help their business, the technology practically sells itself.

Brian Dobben, a welding engineer for Flowserve’s Flow Control Division, could see the value as soon as he saw our camera in action.

It’s worth its weight in gold. It’s just way too valuable not to have,” he recently told us.

Dobben credits Xiris’s cameras with significant cost and time savings, a higher level of safety, and more-effective operator training.

He also appreciates that we travelled from Ontario, Canada to North Carolina, U.S.A. to demonstrate the weld cameras and show personnel how to use the technology (it’s so intuitive, it doesn’t take a tremendous amount of training). Brian was also impressed with our quick turnaround on a necessary repair after a mistake by one of their operators.

We believe our high dynamic range (HDR) weld cameras can increase the efficiency and profitability of any welding operation, and we are committed to making our cameras a game-changing solution. But we don’t just sell cameras, we will do everything possible after a sale to help our customers reap maximum benefit out of them as possible—and that’s a lot of benefit.

To read Brian’s full account of his experience with Xiris—and to get a feel for what we could do for you—we invite you to download this testimonial.

10 Reasons Why You Should Add a Weld Camera to Your Classroom

Posted by Cameron Serles on Thursday, May 30, 2019 @ 01:00 PM

Adding cameras to view and recording welding is a constant desire of progressive welding schools. However, for many years, there was a lack of the appropriate camera technology with High Dynamic Range imaging capability to properly image welding and display it on a standard 8-bit monitor. The Xiris Weld Camera has overcome this with a combination of advanced electronics and software that map the output to a computer monitor for best viewing results, presenting 10 compelling reasons why Instructors should add a weld camera to their program:

  1. A more-enjoyable, “high-tech” learning experience. By introducing cameras into your training curriculum, students will appreciate the modern approach to training an old skill. The result - enhanced prestige for your weld training facility.
  2. Use of recorded welding videos in the classroom. The ability to repeatedly view, and learn from, recorded demonstrations of good and bad welds can improve the overall effectiveness of your learning program.  Imagine having an ongoing source of video material for multiple classroom discussions, or to recreate lessons of key concepts.
  3. A clear view of all the features of the weld process. Never again worry during welding instruction that all students can see what is being taught.  A camera output to a large display makes all the features of a weld visible to everyone in your class.
  4. Better use of classroom layout. No more worry about classroom space, how many students can fit around a particular weld demonstration and how close they can be to the demonstration.
  5. Better capability to demonstrate new or subtle welding techniques. By building up a library of various techniques, students could review the videos of the best or newest welding technique possible.
  6. Reduced material consumption. Use less welding consumables by being able to minimize the amount repetitive arc on-time by students and instructors of the same welding process.
  7. Better curriculum development. Using cameras provides a whole new dimension in developing a better curriculum for welding courses by allowing instructors to employ digital video content in their classroom.
  8. Differentiation from schools without Weld Cameras in classrooms. Let’s face it – attracting students is a tough job and your school is competing with other schools across town and around the world.  The more appealing you can make your program will raise its appeal to prospective students.
  9. More students moving through existing facilities, faster. By providing students live and recorded content on a large display, more students can be learning via video.  The learning via video can happen while other students learn by doing, reinforcing the learning experience and doubling student throughput.
  10. Testing and verifying of new processes and techniques. When new equipment, process or technique is presented to your school, instructors could make a new video to test out the equipment or process, setting a standard for students to attempt to emulate.

With so many powerful reasons to introduce a weld camera into your curriculum, why wait?
