In recent years, with the continuous development of laser technology, laser welding technology has been widely applied in automotive production. Compared to traditional spot welding technology, laser welding technology has higher accuracy and efficiency. In automotive manufacturing, laser welding machines can accurately weld components together, thereby improving the overall quality and safety of the car.

Compared with traditional spot welding technology, laser welding technology generates more concentrated heat during the welding process, thereby reducing deformation and distortion during the welding process, and also reducing thermal damage to materials during the welding process, greatly improving welding quality and accuracy. In addition, laser welding technology also has higher welding speed and less energy consumption, which can effectively reduce the production cost of automobiles and improve the production efficiency of enterprises.

Overall, the application of laser welding technology in automotive production has been widely recognized, with higher welding quality, higher production efficiency, and lower production costs. It plays an important role in improving the overall quality and safety of automobiles. Therefore, in automobile production, enterprises should actively adopt laser welding technology to continuously improve product quality and production efficiency, in order to meet consumers' demand for high-quality cars. The application of laser welding technology in automotive manufacturing has also driven technological innovation in the automotive industry. Compared to traditional spot welding technology, laser welding technology can achieve higher accuracy and stronger connection strength, and can maintain the stability of welded joints for a longer period of time. Therefore, it is widely used in the welding of lightweight and high-strength materials in automobiles and innovation in automotive design.

Meanwhile, laser welding technology can also improve the production efficiency of automotive manufacturing. Traditional spot welding technology requires a large amount of manual operation and maintenance, and requires multiple adjustments and repairs to the welding points, resulting in an increase in manufacturing costs. Laser welding technology can achieve automated production processes, reduce the need for manual intervention, and improve welding efficiency and product quality. In addition, laser welding technology also has the characteristics of environmental protection and energy conservation, making automobile manufacturing more sustainable and environmentally friendly.

Overall, laser welding technology has more advantages compared to traditional spot welding technology, enabling more efficient, stable, and sustainable production processes in automotive manufacturing. At the same time, it can also reduce the cost of automotive manufacturing and improve its competitiveness. With the continuous development of technology, it is believed that laser welding technology will play an increasingly important role in future automotive manufacturing. For traditional spot welding technology, the strength of the solder joint largely depends on the welding time and current, so it is difficult to ensure welding quality and stability. Laser welding technology, on the other hand, utilizes a laser beam to instantly melt the surfaces of two metal components and then allow them to cool and combine. This technology can not only achieve high-strength welds at the welding points, but also better control the welding time and depth, thereby achieving better welding quality and stability.

However, it should be pointed out that the application of laser welding technology in automotive production is still in a relatively early stage, and its cost and technical complexity are still one of the factors restricting its widespread application. In addition, although laser welding technology can reduce the production cost of automobiles, it still needs to be combined with traditional spot welding technology to be better applied in various aspects of automobile manufacturing.

Laser welding is mainly used for body welding and splicing blank plate welding. If there is a large amount of spot welding in the body assembly, two welding heads are clamped at the edge of the workpiece for welding, with a flange width of 16mm, while laser welding is a single side welding, which only requires 5mm. Spot welding should be laser welding, which can save 40 kilograms of steel per vehicle. Two 0.8mm steel plate stamping parts are welded using traditional spot welding, with an average of 20 points per point. Min, welding distance is 25mm, speed is 0.5mm/min, and laser welding speed can reach over 5m/min. The use of laser welding technology not only reduces costs but also greatly improves production efficiency.

In summary, laser welding machines have brought enormous economic benefits to the automotive manufacturing industry. With the gradual maturity of laser welding technology, major automobile manufacturers have without exception applied laser welding to automotive production lines.
