Despite its significant advantages, achieving perfect results also requires overcoming certain challenges:

1. Extremely High Assembly Precision Requirements (The Most Critical Point!)

Laser welding has a small molten pool and solidifies quickly. Therefore, it has a very low tolerance for gaps between workpieces. Typically, the gap must be less than 0.1mm or 10% of the plate thickness. Excessive gaps can result in weld penetration, undercutting, or undercutting. This requires high-precision pre-processing (such as cutting and bending) of the workpiece.

2. High Equipment Investment Cost

The initial investment in an industrial-grade laser welding system (laser, robot, worktable, etc.) is significantly higher than that of traditional welding equipment.

3. Different Operator Skill Requirements

Operators must understand the matching of laser process parameters (power, speed, focus position, shielding gas), rather than the manual skills of traditional welding. Programming and debugging skills are even more crucial.

4. Risk of Reflection

Stainless steel, especially shiny surfaces, has a certain degree of reflectivity to laser light, which can damage laser optics. High-quality lasers are often equipped with anti-reflection protection.
