DocumentDocument1. Introduction 1.1 Overview OTOS Co. Ltd manufactures two kinds of welding camera models for automatic or semi-automatic arc welding(robot or carriage welding). The first model's name is WGC200 and the second model's name is WGC400. These models differ only in the communication method, and all other specifications are almost same. These camera models are cameras that apply high dynamic range(HDR) technology, a technique that darkens extremely bright images and brightens dark areas around the arc in arc welding. These camera models can capture much clearer images than other HDR cameras on the market. Most comparable HDR cameras on the market are equipped with auxiliary lighting and cooling systems, so they are heavier and larger than Autos' welding camera. Therefore, because Autos cameras are the smallest, they are almost unaffected by interference from JIGs in automatic arc welding. These cameras are used by attaching them to a torch mounted on a robot or carriage, or to a head to which a torch is attached. Most HDR cameras that can be compared are black and white cameras, while Autos' cameras are color cameras. The image resolution of comparable HDR cameras is 1440x1024 or lower. Autos' welding cameras can capture clearer images because they have Full HD resolution (1920x1080). Comparable HDR cameras do not allow users to adjust the images they capture. Autos' welding cameras provide users with the ability to easily adjust the image quality to their desired quality. [FIG. 1.1.1] GTAW [FIG. 1.1.2] PAW [FIG. 1.1.3] GMAW WGC200 uses HD-SDI communication method, and WGC400 can use both HD-SDI communication method and Wi-Fi communication method. These cameras are equipped with image sensors that can control dynamic range. When the camera's shutter operates, three images with three different exposure time lengths are captured almost simultaneously. When compositing the three captured images, the bright part is taken from the image captured with a short exposure time, the image part with a medium bright area is taken from the image captured with a medium exposure time, and the image part with a medium bright area is taken from the image captured with a long exposure time. This involves taking image parts in dark areas from an image and compositing them. Therefore, these cameras have ultra high dynamic range (U-HDR) characteristics of over 140 dB. WGC200 (WGC400) can overcome very strong arc light and obtain clear images around the weld zone (melted zone). Therefore, it is possible to extract the width of the weld bead, the arc length, and the amount of error in the position between the electrode position and the welding seam from the real-time captured image. WGC200 (WGC400) provides four types of focusing lenses (focal lengths of 8, 12, 16, and 32mm) to accommodate the user's shooting environment. Users can adjust the distance between the camera and the welding point and capture images of the field of view they want by installing an appropriate focusing lens. [FIG. 1.1.4] WGC200 [FIG. 1.1.5] WGC400 1.2 Features of the WGC200 (WGC400) camera WGC200 (WGC400) is a camera with the following features: 1.2.1 Image clarity Color camera with Full HD (1920×1080) resolution. 140+ dB U-HDR which composite 3 images captured at 3 different exposure times. 1.2.2 Various Field of View (FOV) Three types of imaging lenses with focal lengths of 8, 12, and 16mm are provided as standard. A lens with a specific focal length can be applied, allowing the user to acquire images of the desired FOV. 1.2.3 External transmission method of captured video If the PC's image grabber board or PC has an HD-SDI communication port, captured video can be transmitted directly to the PC. If your PC does not have an HD-SDI port, captured video can be transmitted to the PC through an SDI to USB converter. Captured video can be transmitted without loss even at a long distance (100m) If multiple cameras are used, captured video can be transmitted to a PC at the same time up to 4 channels using the QVM converter. QVM converter converts HD-SDI communication to HDMI, USB3 and GiGE communication. 1.2.4 Adjustment of video image quality If the image is captured upside down when the camera is mounted on the torch mount, the captured image can be flipped vertically. If the left and right sides of the captured image appear reversed, you can adjust the horizontally captured image to be reversed. Helps set the camera's shooting angle by displaying horizontal and vertical grid lines on the captured video image. The sensitivity of the photo sensor can be adjusted to recognize arc on/off. By adjusting the luminance of the captured video image, the overall image can be captured brightly or darkly to achieve the image quality desired by the user. 1.2.5 Auxiliary lighting Do not use any Auxiliary lighting. Capturing clear images with U-HDR control by using only arc light as a light source Since auxiliary lighting is not used, a cooling system is not required (camera miniaturization) 1.2.6 Application to arc welding process Securing durability against high voltage and high frequency generated from Gas Tungsten Arc Welding (GTAW) or Plasma Arc Welding (PAW) Automatic switching between arc on and arc off modes Can be mounted on a welding torch. Minimized interference from welding automation peripheral devices due to ultra-small size. Ease of installation using a dedicated camera mounting jig. 1.2.7 Extraction of real-time welding information from arc welding video Clear welding video images can be captured even in flux cored arc welding (FCAW), where a large amount of fume is generated during welding. When using an appropriate image processing program based on a clear image of the weld periphery, the arc length, width of weld pool (width of bead), and the amount of error in the position between the electrode position and the welding seam can be extracted in real time. In GTAW or PAW, it is possible to control a constant arc length by using arc length information from video images rather than using voltage information to control the arc length. Since the melting amount can be recognized using bead width information, the welding speed of the carriage or robot or the current setting value of the welding power supply can be automatically adjusted to control the desired melting amount. If information such as bead width information, welding current, and welding speed is used, depth of weld or weld strength can be predicted through deep learning. It is possible to track the welding line of a carriage or robot using the positional error amount information between the position of the electrode and the welding seam. Therefore, welding defects do not occur fundamentally. 1.3 Benefits of WGC200 (WGC400) 1.3.1 Clear video image The welding arc and its surroundings, which were too bright to be seen, can now be clearly seen. Real-time, high-quality visualization of the welding process All details can be seen clearly without being affected by the strong bright light generated during the welding process. 1.3.2 Welding process control in real time It is easy to extract the information necessary for controlling the welding process from the captured clear image using an image processing algorithm. It is easy to extract the information necessary for controlling the welding process from the captured clear image using an image processing algorithm. Seam tracking control is possible without using a laser vision sensor. Melting amount can be controlled using bead width information. 1.3.3 Management of welding phenomena (quality) By storing the extracted images, information, and predicted quality on the server, you can quickly identify the cause and respond when a defect in welding quality occurs. Problems and defects in the welding process can be recognized from saved images. The gap, the position of the welding electrode, the balance of the melt pool, and the feeding status of the welding wire can be checked. It is possible to document reports for quality assurance to customers. 1.3.4 Efficiency of production resources It is possible to optimize and increase efficiency of various costs invested in the production of welded products. Saving time and resources (materials, work processes) Reduced costs of downtime or production loss due to defects and increased productivity Reduction of non-destructive testing costs through welding quality assurance Quick problem solving 1.4 Application areas of WGC200 (WGC400) 1.4.1 Real-time control/management field 1) Arc welding Automatic or semi-automatic Arc Welding (GTAW, GMAW, Plasma Arc Welding (PAW), Hardfacing or overlay welding) using robots and carriages.
