In the manufacturing of engineering vehicles, welding is an indispensable process that directly determines the product’s service life and safety. For tank-type structures such as fuel tankers and cement mixers, weld seams are often long and curved, demanding high precision and consistency. During traditional tank welding, operators find it difficult to observe the molten pool directly, making it hard to detect issues such as weld deviation, incomplete penetration, or poor bead formation in real time. To address these challenges, Weld Navigator® has developed a welding molten pool monitoring camera system that enables real-time visualization and controllability of the welding process, achieving high levels of automation and stability in tank welding. I.

In the field of industrial automation, laser displacement sensors are widely used in dimensional measurement, positioning control, and appearance inspection due to their high accuracy, fast response, and non-contact measurement advantages. Based on different measurement methods, point laser and line-scan laser sensors are two common types. Today, let’s follow Weld Navigator® to learn how to choose between point and line-scan laser displacement sensors for real-world applications. 1. Difference in Working Principle A point laser displacement sensor uses the laser triangulation principle. It projects a single laser spot onto the surface of an object, and the sensor calculates the distance by detecting the change in the position of the reflected light. It measures one point at a time, featuring a simple structure, high accuracy, and fast response speed. A line-scan laser displacement sensor, on the other hand, emits a laser line and simultaneously captures height information along the entire line on the object’s surface, forming a profile line. By moving either the sensor or the workpiece, it can generate a complete 3D shape of the object, making it suitable for surface contour and cross-section measurements. 2. Advantages and Application Scenarios Advantages of Point Laser Displacement Sensors High accuracy, fast response, and easy installation Compact design with relatively low cost Suitable for single-point distance, height, thickness, and displacement measurements Typical applications include: Part height detection, thickness measurement, plane positioning, assembly gap inspection, and robotic alignment. Advantages of Line-Scan Laser Displacement Sensors Captures multiple data points simultaneously to form a surface profile Detects complex surface shapes and contour deviations Ideal for large-area, curved, or 3D surface measurements Typical applications include: Sheet contour inspection, weld seam tracking, shape measurement, surface defect detection, and 3D scanning. 3. Selection Recommendations Choosing the right laser displacement sensor depends primarily on

With the rapid growth of smart home products, electric kettles have become an essential household item, where both appearance and sealing quality are critical. In particular, during the inner tank circumferential welding process, sealing strength, joint integrity, and aesthetic quality are all vital.

In modern industrial automation, high-precision and non-contact displacement measurement technologies are drawing increasing attention. Thanks to fast response and micron-level accuracy, laser displacement sensors have been widely applied in dimensional inspection, positioning, and 3D profile scanning. Weld Navigator®’s self-developed laser displacement sensor, based on the principle of laser triangulation, provides reliable and efficient solutions for displacement and dimensional measurement. Today, let’s take a closer look at how laser displacement sensors work. Principle of Laser Triangulation The core working principle of a laser displacement sensor is laser triangulation, which calculates the geometric relationship of the triangle formed by the emitted laser, reflected laser, and receiver to precisely determine the target’s positional changes. The main steps include: Laser emission: The sensor emits a laser spot or line onto the target surface. Reflection collection: The surface reflects the laser, which is then captured by a lens and projected onto the image sensor. Position calculation: As the distance between the sensor and the target changes, the reflection spot shifts on the image sensor. Triangulation: Based on geometric relations, the system quickly calculates the actual distance between the object and the sensor, enabling highly accurate displacement or height detection. Laser displacement sensors not only eliminate wear and error caused by contact measurement but also operate stably under high-speed motion conditions. Advantages of Weld Navigator® Laser Displacement Sensor With long-term dedication to industrial inspection R&D and applications, Weld Navigator® has developed laser displacement sensors featuring several key advantages: High-precision detection: Advanced optical design and signal processing algorithms achieve micron-level accuracy.

In the transformation of manufacturing toward intelligence and automation, traditional welding methods are gradually unable to meet the demands of high-precision welding tasks. This is especially true in exquisite steel welding, where requirements for weld quality are far more stringent. Conventional methods that rely on manual experience or fixed programming often struggle to achieve stable and consistent results under complex conditions. To address this, the Weld Navigator® laser seam tracking sensor provides a brand-new intelligent solution for exquisite steel welding. Principle of Laser Seam Tracking The Weld Navigator® laser seam tracking sensor projects laser beams and uses high-precision imaging to capture the dynamic changes of weld position and the molten pool in real time. Based on advanced algorithms, the system quickly identifies weld features, calculates them, and extracts three-dimensional data such as weld center, width, depth, and groove shape. It then outputs deviation information to the Chaifu welding robot, enabling automatic path correction. This effectively avoids common problems such as weld deviation and torch misalignment, ensuring a precise and stable welding process. Challenges of Exquisite Steel Welding Exquisite steel, as a high-quality structural material, offers advantages such as high strength and low deformation. It is widely used in high-end equipment, precision instruments, and architectural curtain walls. However, its welding poses unique challenges: Strict assembly precision: Gaps and misalignment during part assembly must be controlled within very small tolerances, as even minor deviations can lead to burn-through, incomplete penetration, or poor weld formation. Thermal deformation: Small deviations may cause material distortion, rendering pre-set welding paths invalid. Surface reflectivity: Conventional vision systems often struggle to accurately detect weld positions due to reflective surfaces. Dependence on skilled workers: Welding adjustments often rely heavily on experienced welders, which lowers productivity. Weld Navigator® Solution To tackle these challenges, Wel

Welding, as an indispensable part of modern manufacturing, directly affects the safety and reliability of products. In the past, ensuring welding quality relied heavily on the experience and visual observation of welders. This not only placed high demands on personnel skills but also was easily influenced by factors such as environment, angles, and lighting under complex conditions, leading to untimely monitoring and insufficient accuracy. With the advent of the era of smart manufacturing, how to achieve precise monitoring and control of the welding process has become a key focus of the industry. In response, Weld Navigator® has developed a high-dynamic welding camera, an innovative product designed for welding pool monitoring and intelligent manufacturing.
