With the continuous development of modern manufacturing industry, welding, as a common connection process, has a very important position in product manufacturing. However, there are some problems in the traditional welding method, such as unstable strength of welded joint and great thermal influence of welding process on the product. Therefore, in order to improve product reliability, innovative laser welding machine has become one of the research hotspots in the field of welding technology in recent years.
Laser welding is a technology that uses the heat source of the laser beam to heat and melt the welded joint. Compared with traditional welding methods, laser welding has the following advantages: high energy density, fast welding speed, low heat input. These advantages make laser welding widely used in the manufacturing industry.
First of all, the laser welding machine uses a high energy density laser beam for welding, which can make the joint area reach high temperature in a very short time, so as to achieve rapid melting and welding. Compared with traditional welding methods, the welding speed of laser welding can be increased several times or even more. This method is suitable for small space parts that require efficient connection, such as electronic devices, microchips, etc. Due to the shortened welding time, the production efficiency of the product has been significantly improved.
Secondly, laser welding has the advantage of low heat input. In the traditional welding method, the welding speed is limited due to the great influence of oxygen and nitrogen in the atmosphere on the solidification rate of the molten pool. The heat input of laser welding is low, and the solidification speed is faster, which can effectively reduce the heated area of the welded joint and reduce the thermal effect, so as to improve the quality and strength of the welded joint. This advantage of low heat input makes laser welding suitable for welding parts that require high thermal deformation of products, such as automobile engine cylinder blocks, spacecraft parts, etc.
The laser welding machine also has the characteristics of stable strength of welded joints. In traditional welding methods, the strength of the welded joint is often affected by the uneven shape of the weld during the welding process. Laser welding through the high energy density of the laser beam and precise control of the welding process parameters to ensure uniform weld shape, thereby improving the strength and stability of the welded joint. The improvement of strength and stability makes the product have higher reliability during use and extends the service life of the product.
In addition, the laser welding machine can also realize automatic control during the welding process. Through the automatic control system of laser welding machine, the precise control of welding parameters can be achieved to ensure the quality and consistency of welding joints. Compared with manual welding, automatic control can reduce the error of manual operation and improve production efficiency and product quality.
In summary, the innovative laser welding machine has obvious advantages in improving product reliability. The characteristics of high energy density, fast welding speed and low heat input make laser welding suitable for welding joints of various materials and shapes. In addition, the improvement of strength stability and the application of automatic control system further improve the quality and stability of welded joints. With the continuous improvement of product reliability requirements, innovative laser welding machines will be more widely used and developed.
