Intelligent manufacturing is actually another term for Industry 4.0. Roughly speaking from 1.0 to 4.0 of the industry, the automobile industry is the leader of the manufacturing industry, followed by the 3C industry. This echelon has the highest manufacturing level, which is generally between 2.0 and 3.0. Individual vehicle companies can build new production lines. Around 3.5, auto parts will be relatively low.
The purpose of intelligent automobile manufacturing is very clear, that is, to improve the production, management, safety production, quality control, energy saving and consumption reduction of enterprises, realize lean production, promote the overall manufacturing level of automobile enterprises, and achieve 4.0.
With the development of laser application technology, laser welding technology is widely used in many fields such as consumer electronics, packaging, shipping, aerospace, etc., especially in the field of automobile manufacturing, such as automobile door welding, roof, side frame, parts and other applications.
Modern automobiles require not only practical performance, but also economical beauty. The traditional welding methods are low in efficiency, variability, and low precision, making it difficult to meet the current needs of refined welding and low-cost processing in automotive intelligent manufacturing.
Laser welding technology uses a high-energy density laser beam as a heat source. It is a welding method with high welding accuracy and high efficiency. It has obvious advantages in automobile manufacturing and is becoming more and more popular.
Advantage 1: Reduce processing costs
Automotive welding is to combine various pre-made structural parts by welding or riveting. Modern laser welding technology can effectively reduce the number of solder joints, optimize the amount of materials, reduce the weight of parts, and reduce costs.
Advantage 2 Improve production efficiency
Laser welding can achieve computer or digital control, precise positioning, fast welding speed, and the welding speed can reach tens of meters per minute, which helps to directly shorten the processing and manufacturing cycle and improve production efficiency;
Advantage 3 High welding quality, reducing unnecessary decoration
The laser beam can weld a small range of parts. After welding, the body sheet metal materials are integrated, the surface is smooth and tidy, and the overall texture does not need to be covered by additional decorative strips.
Advantage 4 Reduce the impact of tool loss and deformation
Laser welding technology is different from the general contact welding method. There is no need to use electrodes in the process of applying laser welding technology. It has very little impact on the loss and deformation of the machine. It can greatly reduce the heat input and reduce the heat generated by heat conduction. The incidence of adverse effects.
