Due to the increasing complexity of battery production, the number of scratches generated during the production process has increased. These scratches have caused the area around the tank mouth to become dirty, reducing the welding quality of the top cover. Initially, one company SDI used cotton with cleaner to clean these scratches, but the low efficiency forced them to seek other more efficient ways. Laser cleaning, due to its efficient and environmentally friendly advantages, was used by the company SDI to clean all scratches around the shell and remove other unnecessary materials. It is reported that the company SDI is continuing to develop its fifth generation battery production process. So far, Z-type stacking and label welding have been applied in production, and laser technology is also planned to be applied to the cutting process of battery cells to improve the yield rate of batteries.

Laser in medicine refers to the use of stimulated emission amplification to generate high coherence and intensity monochromatic light. Laser has a wide range of applications in the medical field.

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.
