Fiber laser has become the tool of choice for many advanced and industrial batch welding applications. It can serve many mature industries and adapt to rapidly growing emerging markets. In the booming electric vehicle industry, the high-speed, precise, and high-consistency welding capabilities of fiber laser pointer are driving factors to improve the accessibility and overall performance of commercial electric vehicles. In other more mature industries, the advantages of using fiber lasers are well known. The many advantages of modern industrial laser technology, such as increasing output, better design flexibility, and ultra-high energy efficiency utilization, are continuously promoting the development of this technology in metal joining technology.
For the forward-looking manufacturers who have already fully utilized the advantages of laser welding, the next step is how to further increase output and stay ahead of the competition. The optimization of intelligent manufacturing industrial processes requires high-quality online data collection. In order to realize the automation and decentralization of decision-making, as the "eyes and ears" of the laser welding process, the demand for this technology is increasing.
In the context of explosive growth in the electric vehicle industry, this demand is particularly evident. Traditional electric vehicle welding processes involve many challenges: non-ferrous metal alloys, mixed materials, and strict mechanical and electrical performance requirements for each joint. In addition, since each finished component requires a large number of individual welds, only a small margin of error can be allowed. Strict welding requirements, as well as the huge cost and difficulty of disassembling electrical components during destructive testing. If the manufacturer can produce high-quality qualified products at the first attempt, it will have a significant advantage.
Intelligent manufacturing is different from the open-loop characteristics of traditional development and deployment processes, that is, by designing a reliable process and carefully controlling all input parameters on the production line to achieve as close to the correct operating conditions as possible. Intelligent manufacturing relies on real-time collection and sharing of information technology , This technology can continuously provide status feedback of each subsystem, and ultimately improve transmission efficiency.
When the green laser pointer welding results are inconsistent, the measuring device can continuously measure and report the process conditions during the production process, so as to achieve rapid intervention and even automatic repair. The advantages of this method include increasing production, reducing reliance on follow-up quality inspection links (and consequential costs and lag), and increasing confidence in the finished product.
Versatility is another key advantage of this technology. The measuring beam can be measured before the laser pointer beam to obtain pre-welding information. It can also be measured after welding to confirm the surface quality of the finished weld. It can even generate a 3D image of the sample by scanning, with unprecedented simplicity and accuracy.
