Laser welding is mainly used in automotive manufacturing processes in three main ways: laser welding of body assemblies and subassemblies, laser welding of plates of unequal thickness, and laser welding of automotive parts.
Laser welding of car bodies mainly consists of assembly welding, side panel and roof welding, and subsequent welding. In the automotive industry, the use of laser welding can reduce the weight of cars, improve their maneuverability, and reduce fuel consumption; on the other hand, it can improve product quality and technological advancement.
Laser welding is a process in automotive body design and manufacturing where sheet metal of varying thicknesses, materials, and properties (either similar or different) is laser-cut and assembled into a single unit based on specific design and performance requirements. This unit is then stamped into a specific body component. Currently, laser-welded sheets are widely used in various parts of the automotive body, such as trunk reinforcement panels, trunk inner panels, shock absorber mounts, rear wheel arches, side panel inner panels, door inner panels, front floor, front longitudinal beams, bumpers, crossbeams, wheel arches, B-pillar connectors, and center pillars.
Laser welding of automotive parts offers advantages such as minimal deformation at the welded area, high welding speed, and no need for post-weld heat treatment. Currently, laser welding is widely used in the manufacture of automotive components such as transmission gears, valve lifters, door hinges, drive shafts, steering shafts, engine exhaust pipes, clutches, turbocharger axles, and chassis.
To meet the laser welding needs of the automotive industry, Han's Yueming Laser has developed and provided the HyRobotw20 3D robotic fiber laser welding machine.
It adopts original imported industrial robots with high positioning accuracy, large processing range, and six-axis linkage to realize the welding of three-dimensional automotive parts.
The robot arm is controlled via a handheld terminal. The machine has a compact structure and can operate efficiently even in harsh and restrictive environments.
A non-contact weld seam tracking system is configured to detect and correct weld seam deviations in real time, ensuring welding quality.
Based on the customer's working conditions, we design reasonable safety protection devices to effectively prevent laser radiation from harming personnel during the welding process.
It can be designed for multi-station collaborative work with alternating loading and unloading; the highly flexible welding system can realize automated control and long-distance welding, improving automotive welding efficiency.
