Laser welding technology, as a crucial process in modern manufacturing, has shown remarkable development in both technological innovation and application fields in recent years, bringing a qualitative

Recently, Markets And Markets released a five-year assessment report on the global laser industry. According to the report, the global laser technology market size is expected to reach $20 billion in 2024 and is expected to reach $29.5 billion by 2029, with a CAGR of 8.0% during the forecast period. The reasons for the forecast market growth of the Global Laser Technology market include: increasing demand for laser technology in the healthcare industry; Compared with traditional material processing methods, laser technology has better performance.

Thick plate (thickness ≥20mm) welding plays a key role in large-scale equipment manufacturing in important fields such as aerospace, Marine ships, rail transit, etc. These components are usually characterized by large thickness, joint form and complex service environment. Welding quality has a direct impact on the performance and life of the equipment.

For materials up to 30mm thick, the researchers are actively developing an efficient multi-laser beam welding technology, through the clever combination of three laser beam sources, to build a unique root layer and filler layer welding process. With custom beam shaping technology, they are able to precisely control the characteristics of the molten pool, such as temperature, solidification process and microstructure, to fundamentally prevent the occurrence of thermal cracks and achieve high-quality crack-free welding.
