Technical Overview of the Welding Seam Detection Device "Roland SND40"

Welding seam detection device for pipes (up to 500mm in diameter), metal sheet coils, electric wires, and wires.

The Roland SND40 uses a non-contact eddy current and leakage magnetic flux sensor to detect weld seams on metal plates, both ferrous and non-ferrous, and can identify the position of welds on pipes with a diameter of up to 500mm. 【Benefits】 ◎ Detection of weld seams that cannot be recognized by visual sensors ◎ Utilizes two technological elements: magnetic flux and eddy currents * A full-surround coil that can also be used for metal rods, wires, and cables is available, accommodating a variety of materials. ● Additional technical data and specifications can be viewed from the 【Download】 section. The manufacturing of coil materials and other long materials (cables and wires) results in elongated products (metal coil materials are welded at the ends, and cable materials use joints), necessitating automatic detection of weld seams. In the case of tubes, cans, or drums, automatic detection of weld seams is required along with positioning of the material for further processing. For example, in the case of pipe materials, there is a signal output function that stops the seam position at a specified angle in preparation for the next bending process. The appropriate combination of sensors for the SND40 enables the detection of longitudinal weld seams in all metal tubes, cans, and drums, as well as the detection of end weld seams in coil materials, cables, and wire materials.

From July 15 (Tuesday) to July 20 (Sunday), 2025, the "42nd Daihatsu Japan Open 2025 Badminton Championships" was held at the Tokyo Metropolitan Gymnasium. We would like to report on the motion capture experience session conducted by Yonex Co., Ltd. at the venue. During the experience session, participants were asked to swing three different types of rackets from different generations, focusing on whether there were differences in their top speeds. The measurement was conducted using the same Raptor-12HS system utilized at the Yonex Performance Innovation Center (Blue Lab). This was a valuable opportunity to experience the research equipment that is not currently open to the public and to see what kind of measurements are being conducted! ---[Yonex Co., Ltd.

Hello, this is the public relations department of KAITAKU Co., Ltd. in Okayama City, Okayama Prefecture! Recently, our wooden lightweight hyper CLT sheet has been officially registered with the Ministry of Land, Infrastructure, Transport and Tourism (NETIS number: TH-250021-A). The decisive difference between hyper CLT sheets and conventional temporary materials lies in the "exit" after their durability period ends. The hyper CLT sheet (NETIS number: TH-250021-A) is not discarded after its role on site is finished; instead, it is reused as chip fuel for biomass power generation. • Made: It is made from **wood (thinned timber)**, resulting in low environmental impact. • Used: It significantly contributes to reducing CO2 on site. • Converted to energy: Once its durability period is over, it becomes chip fuel for biomass power generation, ensuring that no resources are wasted. In this way, a **"complete circular" system** is established that connects materials to energy. Additionally, these initiatives can serve as a strong appeal for creativity related to construction performance. Please try the hyper CLT sheet (NETIS number: TH-250021-A)!

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

About a month ago, I took the Sanyo Electric Railway to the Hanshin Electric Railway express train from Himeji to Osaka on a Sunday. The important point here is that it was a "Sunday." The decisive difference from usual days is that there were "families" on board. I had somewhat anticipated this, but nowadays, almost 100% of parents are completely absorbed in their smartphones, ignoring their children who might be standing behind the driver's seat, shouting, or doing anything else. In fact, they even hand another smartphone to their child, effectively using it as a babysitter. At this rate, it's no wonder that these children will grow up to be adults with communication disorders.

On November 6th (Thursday) to 7th (Friday), 2025, we held the "Human Body Day 2025" at the NAC Image Technology Akasaka Multi-Purpose Space. We have uploaded videos of the highlights from each company and the presentations that took place on the day to our website. We encourage you to take a look. ---[Report on Human Body Day 2025 is here]------------------- https://info.nacinc.jp/jintaiday2025-report ------------------------------------------------------------------------- On the day of the event, participants were able to experience a wide range of products in a hands-on session format, including motion capture, force plates, eye tracking, and human body analysis software. We received numerous comments from attendees expressing high satisfaction, saying, "It was great to gain various information all at once," which makes us very happy. NAC Image Technology will continue to provide "valuable products to our customers." We hope you will join us for our next event as well.
