Improved electric vehicle battery performance is a major factor in the steady growth of electric vehicle sales. Better performance stems in part from recent developments in laser welding of dissimilar metals, which improves efficiency by increasing energy storage, reducing size and maintaining reliability. In fact,   welding less resistive metals   to the standard stainless steel terminals of lithium-ion batteries can reduce resistance and improve battery efficiency. However, traditional resistance spot welding cannot effectively join highly conductive dissimilar metals, such as copper and aluminum, because the resulting intermetallic mixture is brittle. But lasers can do the job with amazing results!     Both CW and pulsed fiber lasers are capable of successfully joining dissimilar metals. The key is to use high power and very short pulses to join the parts without melting the metal. The image below, achieved using a 500W single-mode continuous wave fiber laser, shows a cross-section

Laser welding machines have been widely used in all walks of life in recent years, and their types are also developing rapidly with the advancement of technology. Various types of laser welding equipment meet the welding needs of different industries. We may find them when purchasing The price of the laser welding machine is quite different, so today Huiyao Xiaobian will introduce to you why the price of the laser welding machine is so different. 一、Reasons for the price difference between domestic and imported laser welding machines ​​ 1. Technical differences: With the continuous development of domestic science and technology, my country's laser technology has made great progress, but there is still a certain distance to catch up with foreign laser technology, because there are still some parts in laser welding equipment that need to be imported from abroad. . ​​ 2. Cost difference: From the perspective of the performance of laser equipment, in fact, the performance difference be

As China and many countries around the world put forward the "dual carbon" goal, green and sustainable development has become a global consensus. Under this background, new energy sources are emerging, the penetration rate of electric vehicles is increasing, and energy storage is widely used. From the traditional energy era to the new energy era. ​​         Relevant data from the Ministry of Public Security shows that in the past five years, the number of newly registered new energy vehicles in my country has increased from 650,000 in 2017 to 2.95 million in 2021, showing a rapid growth trend. According to the synchronous data of the my country Passenger Transport Association, in 2021, the wholesale of new energy passenger vehicles in China will be 3.312 million, a year-on-year increase of 181.0%; the retail sales of new energy vehicles will be 2.989 million in 2021, a year-on-year increase of 169.1%. ​​         It is worth noting that in 2022, the subsidy standard for new en
