Observation of metallic tissue through chemical treatment.

You can gain clues about the quality of the product and issues through the organizational shape!

We will introduce the observation of metal structures through chemical treatment. By performing chemical treatment on metal samples, it is possible to clearly observe the metal structure. Observing the structure can confirm the condition of the sample and the history of applied heat and stress, providing clues about the quality of the product and any defects based on the structural shape. In the published catalog, you can find details on the observation of metal structures, such as the macrostructure of aluminum plates and the soldered parts of copper terminals. Additionally, we offer other services such as cross-sectional observation and various analysis services. Please feel free to contact us if you have any requests.

Introducing examples of aluminum welding observations. Internal observations through X-ray fluoroscopy and CT scans provide clearer insights after cross-section preparation!

Here is a case study of the observation of aluminum spot welds. Internal observation using X-ray radiography revealed voids within the weld, and internal observation using X-ray CT confirmed that the voids are located near the center of the weld (between the two aluminum plates). Additionally, by creating a cross-section of the same sample and combining mechanical polishing with chemical etching, we were able to observe the condition of the weld more clearly. 【Summary】 ■ Internal observation using X-ray radiography - Conducted non-destructive testing and X-ray radiographic observation - Voids were observed within the weld ■ Internal observation using X-ray CT - Conducted non-destructive testing and X-ray CT observation - Confirmed that the voids are located near the center of the weld ■ Cross-sectional observation using optical microscopy and tabletop SEM - Mechanical polishing and chemical etching A cross-section tailored to the sample allows for clearer observation. *For more details, please refer to the PDF document or feel free to contact us.

Introducing a case study on the cross-section preparation of large samples (65mm × 28mm) and the observation of their internal structures!

We present an observation case of a large sample (expansion valve) measuring 65mm × 28mm. This sample uses magnetic materials, and due to distortion in the images during SEM observation, we primarily conducted observations using an optical microscope. From the appearance and X-ray radiographic observation, it was found that there are some areas that are not visible in the X-ray. 【Overview】 ■ Appearance and X-ray radiographic observation ■ Cross-sectional observation using an optical microscope *For more details, please refer to the PDF document or feel free to contact us.

We will introduce an analysis example confirming that the welded area has a large distribution of grain crystals.

As an example of EBSD, we conducted an analysis of the cross-section of an aluminum welding joint from the cross-sectional direction, and we would like to introduce it. For a sample where an aluminum plate was spot-welded to an aluminum case, we prepared a cross-section of the weld and performed EBSD analysis. In the distribution of grain sizes, it was confirmed that the weld area has a larger number of large grains compared to the base material. [Analysis Overview] ■ Visualization of Grain Structure - It can be seen that the shape and size of the grains in the weld area differ from those in the base material. ■ Distribution of Grain Sizes - It is confirmed that the weld area has a greater distribution of large grains compared to the base material. *For more details, please refer to the PDF document or feel free to contact us.

Investigation of the joint condition and joining methods of crimp terminals, as well as the types of materials! Introduction to cross-sectional observation and elemental analysis using SEM/EDX.

I would like to introduce the topic of "Cross-sectional observation of copper terminals and elemental analysis using SEM/EDX." We conducted cross-section preparation of the joint area of a copper crimp terminal fixture for resistance measurement, applied chemical etching to the prepared cross-section, and observed the metal structure before and after etching. As a result, we infer that the detected elements are P (phosphorus), Ag (silver), and Cu (copper), indicating that it is a silver-containing phosphorus copper soldering material. *For more details, please refer to the PDF document or feel free to contact us.*

We will introduce an example of analysis using EBSD for screws (Cu2Zn).

The EBSD method allows us to confirm the distribution of crystal sizes and the orientation of crystal orientations. In this case, it was found that there is a significant orientation difference in the valleys of the screw, suggesting that there is a high level of residual stress. Additionally, it was observed that small crystal grains are distributed on the surface of the screw. [Summary] ■ Analysis Method - Observation of crystal structure using EBSD ■ Results - It was found that there is a significant orientation difference in the valleys of the screw. - It is inferred that there is a high level of residual stress. - It was also observed that small crystal grains are distributed on the surface of the screw. *For more details, please refer to the PDF document or feel free to contact us.

An article has been published regarding the case study of the attendance management system "KING OF TIME" implemented at Nichirei Industrial Co., Ltd. ~ In the case of Nichirei Industrial ~ The workload related to attendance management has decreased. With the transition from analog tasks to automated aggregation of working hours and granting of annual leave, we can now focus on our work with peace of mind. Particularly regarding the "punching method," we utilize fingerprint and facial recognition. By using biometric authentication, impersonation is not possible, and I believe the accuracy of attendance has significantly improved. Transparency has been ensured. 【Case Overview】 ■Challenges Before Implementation - Handwritten attendance sheets were used, resulting in input tasks to incorporate data into the payroll system. ■Key Points of Implementation - Systematization has reduced input tasks. Biometric authentication prevents impersonation. *For more details, please refer to the related links or feel free to contact us.

[To the owners of parking lots and parking lot construction companies] "I'm worried about not colliding with pedestrians when exiting the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, particularly at entrances facing sidewalks or roadways, there is a risk of dangerous incidents such as collisions with pedestrians or between vehicles. To alleviate such concerns, Hotron proposes a [Vehicle Exit Warning Sensor] that detects vehicle departures using various sensors and alerts the surrounding area with LED lights and buzzers. The system consists of a simple configuration of "sensor" + "controller" + "switching power supply (24V)" + "LED rotating light." *Please note that a separate control panel is required to include the controller and switching power supply (24V) when using the exit warning system. *We kindly ask customers to arrange for the switching power supply (24V), LED rotating light, control panel, circuit breakers, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. We hope this will contribute to safer vehicle passage for everyone. ◎ For more details, please contact us or download the catalog.

Hotron's vehicle detection sensors allow you to search for products that meet your needs from three categories: "Purpose of Use," "Location of Use," and "Product List." The sensors detect the passage of vehicles and notify you with a rotating light, or switch the display of parking availability. They manage vehicle presence, full parking, and exit warnings in parking lots, contributing to safe driving and smooth operational management within the parking area. They are used in various settings, from coin-operated parking to large-scale parking lots.
