Laser welding 0.5 mm thick stainless steel

[waqasmalik]

Hello there. Hope this post finds you well.
I am welding 0.5 mm thick stainless steel using Fibre laser. I'm consistently getting a burn thru. My joint edges are prepared by Shearing. Any idea of how to weld 0.5 mm thick stainless steel without burn thru.

Best Regards

Waqas

Hey Waqas,
Hope you are doing well!

Welding thin stainless steel (0.5 mm) without burn-through:

1. Reduce laser power.
2. Use pulse mode if available.
3. Slow down welding speed.
4. Maintain a steady hand.
5. Consider using filler material.
6. Back purge with inert gas.
7. Optimize joint preparation.
8. Practice on scrap material.
9. Monitor welding parameters.
10. Consider a shielding gas.
11. Inspect the weld for defects.
12. Seek professional advice if needed.
