Seam tracking and seam finding are two distinct function used in welding automation. While both functions are important for optimizing the efficiency and quality of welding processes, they serve different purposes and rely on different technologies. Seam finding, also known as seam sensing, is a process of detecting the location and orientation of a seam on a workpiece before the welding process begins. This is typically achieved through the use of sensors and software programs that guide the welding torch to the precise location of the seam. The purpose of seam finding is to ensure that the weld is applied precisely to the joint, which is critical for ensuring the strength and integrity of the weld. In addition, seam finding helps to reduce the likelihood of defects such as undercuts, overfills, and burn-through. There are several methods of seam finding, including tactile sensing, wire sensing, and laser sensing. Tactile sensing involves physically touching the surface of the workpiece with a wire or nozzle to detect the seam. This method is simple and reliable, but it is slower than other methods and is limited in its ability to detect joint gaps. Wire sensing is similar to tactile sensing, but it uses a servo motor to move the wire up and down rapidly while the robot moves across the workpiece. This method can detect butt joints that are difficult to find with static wire or nozzle touch sensing, but it requires specific hardware and software. Laser sensing is faster than tactile sensing and can detect seams down to 1/16” thick, but it is limited in its ability to detect joint gaps and cannot find square butt joints. Seam tracking, on the other hand, is a process of following the path of the seam during the welding process. This is accomplished through the use of sensors and software programs that guide the welding torch along the seam in real-time. The purpose of seam tracking is to ensure that the weld is applied precisely to the joint, even if there are variations in the position or shape of the seam. This is important for ensuring that the weld is strong and consistent, even if the workpiece is subject to thermal expansion or other factors that can cause

Applicable Products Mainly used for (axial-centrifugal) fan blade welding Fans are mainly divided into two types: axial flow and centrifugal. With the continuous upgrading of industrial products and the rapid development of high-tech industries, centrifugal fans and axial fans are more and more widely used in industrial products for heat dissipation. The principle of centrifugal fans: airflow The air flows into the rotating blade passage in the axial direction, is thrown to the outer edge of the impeller under the action of centrifugal force, and is discharged from the air outlet. The principle of the axial flow fan: the gas enters the rotating impeller axially, is pressurized, and then is discharged axially from the other side. The large number of applications of fans has accelerated the process of fan welding automation, but the efficiency or quality of mainstream positioning tracking welding is not satisfactory. If the positioning method is used, it may be necessary to search for multiple points due to the influence of the radian of the fan blades. Welding can be carried out only when the location is located, and the cycle of location-seeking welding time will also be relatively long. If the tracking method is used, it is difficult to teach and debug more interference, and the tracking of solder joints is not stable. Its one welding cycle and the final effect cannot meet the customer's requirements.   System Composition Sensor Parameters Video Case Name/Model CXZK-JXB300LS Optical size   Z1 Near view field(mm) 240 Recommended installation distance (mm) 300 Z2 Far view field(mm) 360 A-Near plane view field （mm） 36 Center view field of(horizontal)（mm） 45 B-Far plane view field（mm） 54 Average depth resolution（mm） 0.265 Average width resolution（mm） 0.0504 Communication interface Ethernet/RS485 Support segment parameters 103 Output sample rate（Hz） 33 Operate temperature （℃） -10 ~ 65 Power（W） 4

5.2.1 Weld Seam Tracking Products for Home Appliance Industry - Coaxial Vision System 1. Introduction of the laser welding process The laser welding process is a modern welding method. Compared with traditional welding methods, laser welding has many characteristics, such as less deformation of the welded workpiece, higher welding depth and width, and smaller heat affected area. In addition, the laser welding process will not be affected by the magnetic field, will not be completely limited to the working environment of conductive materials and vacuum, and will not generate a large amount of X-rays during the working process. It is precisely because of the above advantages that the laser welding process plays a very important role in the automobile manufacturing industry, the welding of aluminum alloy and magnesium alloy materials, the plastic processing industry, the shipbuilding industry and other fields. Significantly improve industrial efficiency and product and service quality.   2. Status and Welding Problems Every industry has its limitations, and so does laser welding technology; According to the data collection and analysis of the laser welding industry we have collected, due to the thin materials used in this industry, the high sealing requirements and the narrow welding bead, manual manual welding basically cannot meet the welding requirements of the workpiece, mainly relying on automatic welding equipment for welding. ; However, in the process of automated production, due to the workpiece blanking and assembly, tooling, etc., the consistency of the welding seam position is deviated, and the manual point-to-point efficiency is low. Therefore, the customer hopes to have a set of equipment to realize the real-time deviation correction of the welding process and guide the welding torch. Welding, improve work efficiency and reduce product scrap rate.   3. Solutions after install welding seam tracking The commonly used laser vision seam tracker has problems such as large installation interference and low detection accuracy, and it is not suitable for imposition welding.
