What are the advantages of stainless steel laser welding machines?

In daily life, stainless steel materials are ubiquitous—pots, pans, bowls, chopsticks, and more. Traditional welding methods for stainless steel products, such as TIG welding and resistance welding, often suffer from defects like cracks and heat-affected zones. Next, Wuxi Tuoer Laser will introduce the advantages of using stainless steel laser welding machines.

Stainless steel laser welding machines utilize high-energy pulsed lasers to weld objects. The laser power supply triggers pulsed discharge in a xenon lamp, generating light waves of specific frequency and pulse width. These waves are concentrated by a focusing cavity and radiated onto an Nd³⁺:YAG crystal. The crystal emits pulsed laser light at 1064nm after resonance, which is then expanded, reflected, and refocused for welding.

Laser welding offers the following advantages for stainless steel:

1. High speed, deep penetration, and minimal deformation.

2. Welding can be performed at room temperature or under special conditions, with simple equipment setup. For example, laser beams remain undistorted when passing through electromagnetic fields; welding is feasible in vacuum, air, or specific gas environments, and can penetrate materials like glass or other laser-transparent substances.

3. Capable of welding refractory materials such as titanium, and effectively joining dissimilar materials.

4. After focusing, the laser achieves high power density. When welding high-power components, the depth-to-width ratio can reach 5:1, with a maximum of 10:1.

5. Capable of micro-welding. The focused laser beam produces a very small spot size and enables precise positioning, making it suitable for assembling micro and small components in high-volume automated production.

6. Enables welding of hard-to-reach areas through non-contact remote welding, offering significant flexibility. Particularly in recent years, the integration of fiber-optic transmission technology into YAG laser processing has further expanded the adoption and application of laser welding.

7. Laser beams can be easily split temporally and spatially, enabling simultaneous multi-beam processing and multi-station operations, thereby facilitating more precise welding.
