Laser power supply, as a core process equipment in automobile manufacturing, is driving the industry towards rapid development towards intelligence and precision.

In the field of automobile manufacturing, continuous fiber laser power supply (6kW) has become the main equipment for white body welding due to its high energy efficiency (electro-optical conversion>40%) and stability (current ripple ＜ 1%), which can achieve high-speed welding of galvanized steel plates and reduce thermal deformation by 60%.

Pulse fiber laser power supply is specialized in the field of automotive electronic packaging due to its precise temperature control characteristics (± 0.5 ℃), and is used for welding new energy battery poles. Pulse semiconductor laser power supply is mainly used for precision welding of automotive electronics. Laser power technology is profoundly changing the automotive manufacturing process, especially in strategic emerging fields such as new energy three electric systems and intelligent driving sensors, driving the automotive industry towards higher precision and greater flexibility.

Portable laser marking machines and cleaning machines are playing an increasingly important role in the automotive manufacturing industry, significantly improving production efficiency and process quality. In modern automotive production lines, portable laser marking machines, with their excellent flexibility, can permanently mark various material components: they can engrave permanent QR codes (with a positioning accuracy of up to 0.05mm) on the surface of metal parts such as engine cylinder blocks and gearbox housings. In the powertrain field, high-power laser marking machines can engrave VIN codes with a depth of 0.05-3mm on the surface of engine cylinder blocks.

The portable laser cleaning machine has opened up a new paradigm for surface treatment in automotive manufacturing. In the welding workshop, the 500W pull rod pulse laser cleaning machine can quickly remove the oxide layer on the overlapping surface of the vehicle body, providing an ideal interface for subsequent welding and increasing the strength of the welding point by 15%; In the pre-treatment stage of painting, the local electrophoretic layer can be selectively removed, greatly reducing the pollution caused by traditional chemical paint stripping. Especially in terms of mold maintenance, the cabinet type pulse laser cleaning machine can accurately remove deposited carbides without damaging the mold substrate, shortening the repair cycle by 70%.
