Thanks this means a lot! This is the first kind of video we do like this and we appreciate the feedback!

Hi! In this specific video, you're seeing 3D stereoscopic cameras.

The weld strength varies greatly based on the materials being joined, their thickness, the laser power, and other parameters. Each application is unique and comes with different requirements, so it's impossible to give general numbers. We can reach 200N of shear strength and more. You can find examples of weld strengths here: www.laserax.com/battery-laser-welding-applications As you can see, they vary a lot. If you have a battery welding application and need help, please contact our experts here: www.laserax.com/contact-us

@@Laserax Thank you for your information

Hi there! With laser welding, using a shield gas is not always needed to achieve a high weld quality. The metal melts and cools much faster (almost instantly), so there is a lot less time for contaminants and oxygen to penetrate the welds. Still, using a shield gas like Argon is always beneficial. When we develop a laser welding process, we start without a shield gas and aim to achieve the best welding quality this way. We then add a shield gas afterwards, if needed.

Thanks, we'll pass your message on to Catherine!

Hello there! The laser process you see is removing oxides. The oxide layer is thin so you can't see it, but it needs to be removed before adhesive bonding or it will diminish the bond strength.

Hi Henry! I assume you mean during laser process development as opposed to in the production line. We use a range of tests and measurements to validate weld quality during process development/optimization. The most common ones are cross-section images (SEM), mechanical resistance (force tester), electrical resistivity (four-wire Kelvin measurement), laser weld monitoring data (light reflection), depth of penetration (SEM), and aging tests.

@@LaseraxVery cool. Thanks for sharing, this is the craziest welder I have ever seen.

For the pouch cell tabs, the material is either nickel-plated aluminum or nickel-plated copper. For the prismatic cell casing, it's nickel-plated steel. For the cylindrical cells, it's nickel-plated steel. Hope this helps! Sorry for the late response, we hadn't seen the notification!

Thanks Eaton! Have you tried different surface prep methods for adhesive bonding?

This is a fiber laser!

Hello Christian! 4680 cells can be bought on the internet. The ones you see in the video are "dummy cells" to demonstrate the process. We actually have a good supply of them. If you need specific details on how to order them, you can contact us in private at the following address: www.laserax.com/contact-us

Hello @user-yh4tp5jh4o! It depends on the type of material, the welding thickness, the laser, the robots, and such factors. For most applications, the laser is limited by the robots, and multiple robots can be used to maximize the laser's uptime. You can contact us using the form on this page to discuss your application: www.laserax.com/contact-us

Hello Jian! Yes, we take into account the battery cell's negative shoulder (or rim). Some cells have a round shoulder, some have a flat shoulder, and others are in between. The shoulder's shape differs based on the battery's model and specification. The one shown in the demo has flat shoulders.

@@Laserax interesting 🤔 which models have flat shoulder and which models have a round shoulder? The round shoulder must be more difficult to weld.

@@jianyang2214 You're absolutely right! Actually, round shoulders are more challenging for any joining technology. That's because the contact point between the cell and the busbar/collector plate is harder to reach, so precision is even more important. For the models of batteries, I don't have the answer unfortunately. I hope this was helpful!

Hello Sandesh! The cost of a laser machine varies a lot depending on the laser power and the options included in it, which are specific to each application. If you want a quote for a specific project, please contact us at: www.laserax.com/contact-us

Hello Sarang! The SCARA robots you see in the video move clamping tools with pressure sensors to confirm that the right pressure was applied on every cell and ensure zero gap. This clamping design is flexible and adaptable for various module designs and cell types.

Hello Bill! We specialize in fiber lasers to process metals in high volume production lines, which is why aesthetic textures on plastics are not shown. Textures on metal surfaces are mostly used for practical reasons, not aesthetic ones. They can improve the performance of adhesive bonding and of thermal transfer. Regarding plastics, not all types of plastics react well to fiber lasers; UV lasers are often preferred for example.

That's not how LASERs work

@dusselelite724 Good question! There are indeed technical limitations. The first one is that the laser beam, by definition, needs to be focussed on a single location to do its work. It allows it to concentrate a lot of energy in a small area. Now, it is possible to treat different areas at the same time, but you need multiple laser heads to do that. But you cannot treat all areas at once. In the laser head, mirrors move the laser beam very quickly over the work area. These mirrors are called galvo mirrors. The second limitation is that the laser head can only "see" a certain work area. We call this its field of view. For this reason, depending on the part size, you may need to move the laser head using a gantry system.

@@Laserax Sorry, may I know what is the principle/method you use protective gas for this? how you blow the gas and exhaust ? thank you.

@@kumkumi963 To prevent oxidation of the welds, some manufacturers use a shield gas (like argon) in combination with laser welding. While using a shield gas is not always needed to achieve the required weld quality, it is always beneficial, as it helps reduce the number of defects in the welds. A good practice we use at Laserax is to develop the laser welding process without a shield gas and aim to achieve a good welding quality this way. If shield gas is added afterwards, it will only benefit the process. We use the shield gas demanded by the manufacturer.

The first 13 seconds show the laser engraving process. We then send the part to be shotblasted, and show the result of the codes that have been shotblasted, still readable for traceability. Our process was developed in partnership with the Cascade Die Casting Group and Mercury Marine. It is explained here if you want to know what our special effects are all about! www.laserax.com/laser-marking/shotblast-resistant

¡Hola @renzohernandez1214! Disculpa mi español, este mensaje fue traducido del inglés al español usando DeepL. Sí, el texturizado por láser se puede utilizar para sustituir el chorro de arena al tiempo que proporciona mejores propiedades adhesivas/mejor perfil de anclaje. De hecho, el texturizado láser ofrece un montón de ventajas en comparación con los tratamientos de chorreado abrasivo. En breve publicaremos un documento técnico en nuestro sitio web, pero aquí tiene un breve resumen de las ventajas: Menores costes de consumibles y de funcionamiento, menor cantidad de polvo generado, no se necesitan EPI, mejor control sobre la superficie acabada, no se daña la superficie, mejor eliminación de contaminantes, no es necesario enmascarar, mayor precisión, cambios de configuración automatizados para diferentes necesidades de texturizado y mejor repetibilidad. Encontrará más detalles sobre estos temas en nuestro documento. Estará disponible en unos días en la siguiente página: www.laserax.com/resources/technical-papers

Hello there! We don't have the specific numbers for your question readily available because we would need to perform tests. To give you a general idea, using a 500W laser on aluminum, the deep engraving speed varies between 1.00 mm3/s and 2.51 mm3/s. Speed is mostly affected by laser power, alloy, character size, and character depth. Engraving our logo 2mm deep could be super short or super long, depending on how big we want it. For deep logo engraving in general, and not shotblast resistant engraving, you can find additional information here: www.laserax.com/deep-laser-engraving-metals Shotblast resistant engraving is typically used to maintain traceability on shotblasted parts. With this process, the size of blast particles dictates the size and depth of the characters, so using 2mm deep characters is not necessarily where you want to start. You can find more information on this process here: www.laserax.com/laser-marking/shotblast-resistant

@@Laserax thanks for the information i will call the german support of laserax.

Hey @Nitro 187! We'll take your comment into account for future videos. Hopefully you still liked the demonstration!

@@Laserax Thank you kindly. :)

Hello Spaghettio! Unfortunately, I am not allowed to share details on the spot size for this specific application, but I can tell you that we work with different spot sizes depending on the type of material and its thickness. If you need a laser and want to discuss your application, please contact our laser experts here: www.laserax.com/contact-us Hope this helps!

​@@Laserax hmm, can you evaluate the method, which one is better between using the fixture placed over the top of the busbar and welding as in the video at separate busbars? thank you.

@@kumkumi963 This is a demo video to show the laser process. It is better to use fixtures for clamping to achieve zero gap, as is done in our other videos.

Hello there! The laser modifies the surface finish of the aluminum, which affects how light is reflected. Visually speaking, this "seems" like a change in color. Hope this helps! Let us know if you need help with a project!

Hello Stephan! Laserax manufactures OEM systems for integrators as well as turnkey solutions for manufacturers. We provide training to customers to get them started and support them properly with our products. If you're planning on using lasers, I suggest you read on class-1 laser safety: www.laserax.com/blog/class-1-laser-products-regulations You can also have a look at this post to find out about the different types of laser cleaners available on the market: www.laserax.com/blog/laser-cleaner

Hello Chris! Sorry for the late response! Yes, we can mark the bare metal before anodizing. We actually use a process called laser engraving for this, where we dig into the aluminum. The markings will be readable through the anodized layer. It's also possible to etch the anodized layer without going through it. But whether this can be done depends on the coating's thickness, and we need to perform tests on a case-by-case basis to confirm feasability. Hope this helped! If you have an application in mind and need a laser, you should contact our experts to discuss the details. Here's the link: www.laserax.com/contact-us

Hello Richard! Just saw your message (we don't get notified for replies). These lasers are meant for high-volume production lines. Manufacturers get back their investment in no time for several reasons. Lasers are used to ramp up production, have low maintenance and operating costs, eliminate the need for manual processes, prevent non-quality costs, are used to obtain green subsidies, and have a long operating life so you don't need to replace your equipment all the time.

Hello Joseph! Laser cleaning can definitely be a cost-effective way to replace blasting done on steel sheets. It all depends on the sheets' dimension and on the cycle time available for the laser process. If you have an application in mind, you should contact our laser experts to discuss the details. Here's the link: www.laserax.com/contact-us

Hello there! The short answer is yes, laser cleaning can remove oxides that form on the metals you mentionned. The reason is that the ablation threshold of oxides is lower than the ablation threshold of metals, so you can safely remove the oxides without affecting the metal underneath (if the laser intensity is properly set). If you want more information, I suggest you read this blog post that explains how the process works: www.laserax.com/blog/how-does-laser-cleaning-work

Hello Jay Me! The laser does two things at the same time in the video: it cleans the surface by removing surface contaminants (laser cleaning) and it modifies the surface roughness to increase adhesion, reduce friction or affect other surface properties (laser texturing). Those processes are used to replace typical surface treatments like sandblasting or chemical baths. You can find more information on our website: www.laserax.com/laser-texturing

Actually, the laser does three things in the video! You can also see an example of laser marking at 2mn07 (kzbin.info/www/bejne/fovceYNqm7Srec0), where a logo and serial numbers are etched onto the surface for traceability.

Ciao Paolo! Scusa per il mio italiano, ho usato google traduttore (Google Translate)! Come ogni metodo di pulizia, la pulizia laser può rimuovere solo contaminanti superficiali. Per evitare che contaminanti penetrino nella saldatura, è imperativo che la superficie sia pulita adeguatamente prima della saldatura. È possibile utilizzare la pulizia laser per rimuovere i contaminanti superficiali prima della saldatura. Se sei interessato, guarda questo video per un esempio di pulizia laser in linea subito prima della saldatura: kzbin.info/www/bejne/aZaZfYmBZcyAe7c È inoltre possibile visitare questa pagina per ulteriori informazioni sull'applicazione: www.laserax.com/applications/laser-cleaning-oxide-removal Spero che questo abbia aiutato!
