Automatic laser welding machines are widely used in automotive manufacturing, sheet metal processing, furniture industries, and more. With their user-friendly operation and ease of use, these machines can significantly boost production efficiency and create greater value for businesses. As welding speed remains a key performance indicator during operation, how can we effectively enhance this critical parameter?
Zhang, a manufacturer of laser welding machines in Suzhou, explained that there are three main parameters affecting welding speed: laser power, welding speed, defocus, and auxiliary gas.
Laser power: The higher the power, the faster the welding speed. However, the power depends on the material characteristics and thickness.
Welding speed: This directly affects the processing length within a given time. To ensure fusion depth and weld quality, the power should be adjusted simultaneously to improve speed.
Defocus (off-focus): Once determined, it usually remains stable. The appropriate defocus affects the energy density distribution and the shape of the molten pool, which is the basis for achieving stable high-speed welding.
Auxiliary gas: This effectively protects the molten pool, reduces splatter, stabilizes the process, and ensures the stability of high-speed welding.
If you are in the initial stage of exploring welding process parameters, it is best to use a single-variable control method. During welding, find the appropriate defocus amount and keep it constant, then focus on adjusting and optimizing the laser power and welding speed (the formation of welds is mainly determined by both laser power and welding speed).
In addition to the above parameters, the workpiece itself and processing requirements also affect welding speed.
Welding depth: Deep fusion welding requires high-power or low-speed welding equipment. In this case, we should prioritize the power capacity of the equipment when selecting it. Chinese laser welding machines, such as those produced by Suzhou Luming Laser Equipment, feature advanced power control systems that can respond more flexibly to such requirements.
Spot size: The smaller the spot, the smaller the volume of the marked product. Conversely, the larger the spot, the faster the marking speed.
Welding density: Under the same format, point, and depth, the higher the welding density, the slower the welding speed. This is because the density directly increases the welding area.
Welding range: The deflection area of a large welding mirror increases, which slows the welding speed. The smaller the processing range, the faster the welding speed.
As a leading Chinese manufacturer of laser welding systems, Suzhou Luming Laser has accumulated over a decade of expertise in the field. The company specializes in delivering high-performance welding equipment through rigorous quality control of core components, including lasers and laser galvanometers.
