With the development of science and technology, people's requirements for welding quality are becoming higher and higher. Automated production requires less manpower, improves product consistency, improves product quality, is more suitable for mass production, reduces production costs, and improves production efficiency. However, manual welding is difficult to maintain the stability and consistency of welding work for a long time due to objective and subjective factors such as technical level, fatigue level, responsibility, and physiological limits. Moreover, due to poor welding conditions, the number of people willing to engage in manual welding is decreasing, and there is a trend of a shortage of skilled workers. It can be said that welding robots basically meet the requirements of welding automation.
Firstly, the characteristics of robot laser welding
1. Stabilize welding quality and improve product qualification rate. Before welding different welding pads, the robot automatically recognizes the weld seam and drips the welding material into the weld seam to fill it. The weld seam is beautiful and firm, and the consistency of the welded parts is high, which improves the product qualification rate.
2. Reduce the labor intensity of workers. Welding robots with auxiliary equipment can automatically flip thick plate welds, repeat production, and help workers free themselves from heavy welding tasks.
3. Improve production efficiency. Traditional welding is affected by welding environment and human factors during operation, which slows down the working process and is not conducive to reasonable production arrangements. Welding robots have a high degree of automation and can perform continuous and long-term welding tasks, helping enterprises improve production efficiency.
4. Reduce costs. In traditional welding, welding defect such as under welding, partial welding, over welding, etc. What will happen will increase the material costs of the enterprise. Welding robots can reduce welding materials based on the weld seam, making full use of welding materials while accurately welding. One operator can operate two or three welding robots simultaneously, reducing the labor cost of the enterprise.
2、 Performance advantages of laser welding robots:
1. Robot laser welding machines do not require contact processing and have no external force on welded parts.
2. The laser energy of the robot laser welding machine is highly concentrated, with small thermal effects and thermal deformation.
3. Robot laser welding machines can weld high melting point, refractory and refractory metals, such as titanium and aluminum alloys. And it can achieve welding between different materials.
4. The robot laser welding machine welding process is pollution-free and can be directly welded in the air. This process is simple and practical.
5. The robot laser welding machine has small welding points, narrow welding seams, and a neat and beautiful appearance. After welding, there is no need for processing or the processing process is simple. The weld structure is uniform, with fewer pores and defects, which can reduce and optimize the impurities in the base material. The mechanical strength of welds is often higher than that of the base metal. The mechanical performance, corrosion resistance, and electromagnetic performance of the robot laser welding machine are superior to conventional welding methods.
6. Laser can be accurately controlled with small focusing spot, and robot laser welding machines can achieve high-precision positioning and precision machining.
7. Robot laser welding machines are easy to cooperate with computer numerical control systems or robotic arms to achieve automatic welding and improve production efficiency.
Based on the above content, we can see that robot laser welding machines can bring a lot of help to the production of the entire industry. Welding robots can replace manual labor to complete welding independently. The application of welding robots is becoming increasingly widespread, which is a major trend in the future development of welding manufacturing industry.
