The Effect of Butt Joint Groove Form on Laser Arc Composite Welding of Medium and Thick Plate
01 What is a welded joint A welded joint refers to a joint where two or more workpieces are connected by welding. The welded joint of fusion welding is formed by local heating from a high-temperature heat source. The welded joint consists of a fusion zone (weld zone), fusion line, heat affected z...Read more -
What are the laser welding processes?
Laser welding is a new type of welding method. Laser welding is mainly aimed at welding thin-walled materials and precision parts. It can realize spot welding, butt welding, stack welding, seal welding, etc. Its characteristics are: high aspect ratio, The seam width is small, the heat affected zo...Read more -
History of laser development in China: What can we rely on to go further?
It has been more than 60 years since the first “beam of coherent light” was generated in a California laboratory in 1960. As the inventor of the laser, T.H. Maiman, said, “A laser is a solution in search of a problem.” Laser, as a tool, It is gradually penetrating into man...Read more -
Single-mode-multi-mode-annular-hybrid laser welding comparison
Welding is a process of joining two or more metals together through the application of heat. Welding typically involves heating a material to its melting point so that the base metal melts to fill the gaps between the joints, forming a strong connection. Laser welding is a connection method that ...Read more -
Laser Storm – Future technological changes in dual-beam laser technology 2
1. Application examples 1）Splicing board In the 1960s, Toyota Motor Company first adopted tailor-welded blank technology. It is to connect two or more sheets together by welding and then stamp them. These sheets can have different thicknesses, materials, and properties. Due to the increasingly h...Read more -

Comparison of welding effects of lasers with different core diameters
Laser welding can be achieved using continuous or pulsed laser beams. The principles of laser welding can be divided into heat conduction welding and laser deep penetration welding. When the power density is less than 104~105 W/cm2, it is heat conduction welding. At this time, the penetration dep...Read more -
