Welding is a very difficult process to manage in many companies. Welding positions are generally unstable because welding is very harmful to the eyes, so many workers cannot stay on the job for long, partly because they are afraid of damaging their health, and partly because they cannot handle the physical strain. Therefore, this has become a major concern for many companies.
With the development of technology, welding robots have emerged, primarily replacing human welders. Their main advantages include highly stable performance, large workspace, high efficiency, and strong load capacity. Compared to human labor, welding robots deliver significantly higher quality and efficiency.
A welding robot is an industrial robot that performs welding (including cutting and spraying). According to the International Organization for Standardization (ISO) definition of a standard welding robot, an industrial robot is a multi-purpose, reprogrammable, automated manipulator with three or more programmable axes used in industrial automation. To adapt to different applications, the mechanical interface of the robot's last axis is typically a connecting flange, which can be used to attach different tools or end effectors. A welding robot is essentially an industrial robot with a welding clamp or welding (cutting) torch attached to its last axis flange, enabling it to perform welding, cutting, or thermal spraying.
Welding robots have a wide range of applications, such as in the production of electronic connectors, computer data cables, automotive welding, and small electronic components. The following are some of the main application areas for welding robots.
Mechanical manufacturing field
With the increasing demand for welding in the machinery manufacturing industry, welding work is inherently a dangerous profession due to poor working conditions and high heat radiation. The presence of many large pieces of equipment in machinery manufacturing further complicates welding. Welding robots are automated mechanical devices that perform welding work, reducing the workload of workers and helping to improve the level of automation in the machinery manufacturing field.
Automotive and Auto Parts Sector
In recent years, in order to meet the needs of the public, the automotive industry has shown diversified development. Traditional welding can no longer meet the high welding requirements of automobile and auto parts manufacturing. Welding robots can achieve precise welding of weld seams, and put down just the right amount of welding material to fill the gaps. The weld seams are beautiful and strong. In many modern automobile production workshops, welding robot production lines have been formed.
electronic devices
The field of electronic equipment has high requirements for welding quality. With the increasing demand for electronic equipment, electronic equipment is developing rapidly but also faces severe challenges. Welding robots can ensure production efficiency while maintaining stable welding quality, achieving precise welding of electronic equipment, and improving efficiency by three to four times compared to manual labor.
Aerospace
In aircraft structures, there are nearly a thousand welded components and nearly ten thousand parts. Many of the important load-bearing components of aircraft are welded. The aircraft fuselage is subjected to great pressure during flight, so the welding requirements are quite strict. Welding robots use automatic weld seam tracking technology to flexibly set welding parameters and perform precise welding on aircraft structures.
