Laser seam tracking system

With the development of industrial automation, welding technology is becoming more and more widely used in many industries. However, due to the peculiarities of the welding process, seam tracking has always been an important challenge in the welding process. The weld seam tracking sensors came into being to solve this problem.

First、Principle of weld tracking system

The weld seam tracking system is an automated system. It can track the weld position and trajectory in real time during the welding process, ensuring the accuracy and consistency of the welding process. The system consists of tracking sensors, computer control system, and welding equipment.

The tracking sensor is the core component of the system. It can achieve weld seam tracking by working on different working principles. Among them, the most common types of sensors are laser sensors and vision sensors. The laser sensor tracks welds by measuring the position of the laser spot on the surface of the workpiece. The vision sensor uses cameras to capture images of the surface of the workpiece and track the weld by calculating the position of the weld in the image. Both sensors have their own advantages and disadvantages, and the specific choice should be determined according to actual needs.

Second、The role of the weld tracking system

The main function of the weld tracking system is to ensure the accuracy and consistency of the welding process. Specifically, the seam tracking system can achieve the following functions：

Automatically track weld position and trajectory to ensure accuracy and consistency in the welding process.  Detect defects in the welding process and make timely adjustments to avoid welding defects. Improve welding productivity and quality, and reduce costs.

Third、Application fields of weld tracking systems

Weld seam tracking systems can be applied to many fields. Here are a few typical areas of application：

Automotive manufacturing：

A large number of welding processes are required in the automotive manufacturing process. The weld seam tracking system can guarantee the accuracy and consistency of the welding process, improving production efficiency and quality.  

Shipbuilding：

Shipbuilding is a complex process. Weld seam tracking systems can help guarantee weld quality and reduce wear and tear and maintenance costs during vessel operation.

Petrochemical industry: In the petrochemical industry, welding is an essential process. Weld seam tracking systems can help ensure the quality and consistency of welds and reduce possible security risks.

Power industry: The manufacture and maintenance of power equipment requires a large number of welding processes. Weld seam tracking systems can improve productivity and quality, and reduce costs.

Weld seam tracking sensor plays an important role in industrial automation. It ensures accuracy and consistency of the welding process by tracking weld position and trajectory in real time. It can improve production efficiency and quality, reduce costs, and reduce possible safety risks. Weld tracking systems are widely used in many fields such as automotive manufacturing, shipbuilding, petrochemical industry and power equipment.
