In ancient times, people repeatedly hammered pig iron that was burned red at high temperatures, ultimately converting it into steel. Now, a team led by the University of Cambridge in the UK has revolutionized technology and developed a new method for 3D printing metal, which can program structural changes into metal alloys during the printing process, fine tune their performance, without the need for the thousands of years of "heating forging" process. This method can reduce costs and more effectively utilize resources. The research results were published in the 30th issue of the journal Nature Communications.
A few years ago, when it comes to the new energy industries, the lithium and electric vehicles are the first things, but in fact, the solar energy also belongs to the new energy industry. In 2023, with weak industrial economy growth and laser industry involution and competition, the solar battery laser equipment is gradually increasing, it is becoming a great highlight.
In recent years, with the quick and continuous development of laser industry and its high reliability and low consumption, laser has replaced a sort of traditional industrial equipment.
The traditional welding machine has a great challenge in processing thin stainless steel plates. Due to its small thermal conductivity and low constraint, once the thin stainless steel plate is locally heated and cooled during the welding process, uneven stress and strain will be formed. The longitudinal shrinkage of the weld seam will generate certain pressure on the outer edge of the stainless steel plate.
Laser welding is an important part of laser technology for processing the materials, mainly used in thin wall materials and low speed welding. Compared with other traditional welding technologies, laser welding has such advantages:
In the process of development and use of photovoltaic energy, as a high precision and high efficiency tool, laser is playing an increasingly important role. This article is about to discovery the application of laser technology in photovoltaic energy industry and expect the development outlook of the laser technology.
The combination of ultra short pulse laser and exquisite self-focusing technology provides the required quality and process reliability, making it possible to apply glass laser welding in mass production. The unique and excellent properties of glass make it widely used in various high-tech products in different fields such as biomedical and microelectronics.
In recent years, with the continuous upgrading of technology, the trend of future growth in plastics laser welding has gradually emerged.
At present, many products(including automobile semi-conductors, medical and food industries) have extremely high requirements for processing precision and cosmetic, that made laser welding has been become the necessary process of those products, also make laser welding a further development.
With the rapid development of the handheld laser welding market, a large number of handheld laser welding machines that use water-cooled cooling methods have been sold in the market in recent years.
