Analysis of Factors Affecting Laser Welding Quality

Laser welding technology holds a pivotal position in industrial applications due to its unique advantages, demonstrating extensive versatility that spans virtually all welding domains while supplanting traditional welding methods. Its exceptional welding precision is a key factor in its widespread adoption among manufacturers. Here, I briefly analyze several factors influencing laser welding quality.

First, the beam mode, output power, and stability of the laser source in the laser welding machine are critical. Beam mode serves as the primary indicator of beam quality. A lower beam mode order translates to superior focusing capability, a smaller spot size, and higher power density at equivalent laser power, resulting in greater weld depth and width.

Second, the condition of the workpiece significantly impacts weld quality. Preparing long weld seams is challenging; standard shearing machines often fall short, necessitating precision machining or high-accuracy shearing. Additionally, specialized fixtures must be designed for each specific workpiece. In practical production, these requirements sometimes cannot be met, precluding the use of laser welding technology.
