Since the 21st century, with the continuous development of industrial automation, automatic welding technology has been increasingly used in the manufacturing industry. There are many types of automatic welding systems, the most common of which are robotic welding systems, fixed welding systems and mobile welding systems. Each type of system has its own unique working methods, application scenarios and advantages.

1. Robotic welding system

Robotic welding is currently the most advanced and widely used automatic welding system, which mainly relies on industrial robots to complete welding tasks. The robot's mechanical arm can flexibly perform welding operations in three-dimensional space through precise control.

Working method:

Robotic automatic welding systems usually include welding robots, control systems, welding power supplies, welding heads and related accessories. Through preset programs or real-time programming, welding robots can accurately weld according to the set path, speed and angle. The robotic system uses feedback devices such as sensors and visual systems to monitor parameters such as temperature and welding position during the welding process in real time, thereby ensuring the stability and consistency of welding.

Advantages and applications:

High precision: The robotic welding system can provide consistent welding quality and greatly reduce human errors.

High flexibility: suitable for welding workpieces with complex shapes, the welding path can be easily adjusted to adapt to different welding requirements.

Widely used in automobile manufacturing, precision equipment, aerospace and other fields, especially suitable for large-scale and highly complex production tasks.
 

2. Fixed welding system

The fixed automatic welding system is a system in which the welding tools and equipment are fixed, and the workpiece or welding head is welded on a fixed platform. Usually, the fixed system is used in a standardized and batch production environment, suitable for welding tasks that require high consistency.

Working method:

In a fixed welding system, the welding equipment (such as welding head, welding power supply, etc.) is usually fixed in one position, the workpiece is placed on the workbench, and the welding head operates according to a predetermined trajectory. By using a numerical control system (CNC) or a robot control system, the welding path and welding parameters of the workpiece can be set in advance to ensure the consistent quality of each weld.

Advantages and applications:

Efficiency: For large-scale production tasks, the fixed welding system can complete the welding operation efficiently and stably.

Low cost: Compared with the robot welding system, the equipment investment and maintenance cost of the fixed system are lower.

It is suitable for large-scale production tasks such as pipelines, containers, and steel structures, especially when the size of the welded workpieces is relatively consistent.

3. Mobile welding system

Mobile automatic welding system refers to a welding system in which the welding equipment can be moved within a certain range and the working position can be adjusted as needed. Compared with fixed systems, mobile systems have greater flexibility and are suitable for processing workpieces with larger sizes or irregular shapes.

Working method:

Mobile welding systems usually consist of a bracket or guide rail system with adjustable height and position. The welding head or welding robot moves on the surface of the workpiece to complete the welding work. Through the track or wheel transmission system, the welding head can perform continuous welding along a predetermined trajectory, which is suitable for longer distances or multi-point welding tasks. The mobile system is controlled by programming to ensure accurate welding paths.

Advantages and applications:

Flexibility: It can adapt to larger or irregularly shaped workpieces, especially for tasks that require welding over a large range.

Efficiency: It is particularly suitable for welding long pipelines, large containers or large structural parts.

Commonly used in industries such as shipbuilding, oil pipelines, steel structures, and large mechanical equipment, it can complete welding tasks when the workpiece is not easy to move.

Summary

Different types of automatic welding systems have their own characteristics and are widely used in production. Robotic welding systems are suitable for high-precision and complex welding tasks; fixed welding systems are suitable for large-scale, standardized production; and mobile welding systems are suitable for large or irregularly shaped workpieces and can be welded over a large range.

With the continuous advancement of technology, automatic welding systems will continue to develop in a more intelligent and flexible direction, providing more efficient and precise welding solutions for various industries.
