“Keyhole” mechanism in welding thin plates with a low power CO2 laser |
| |
| Abstract: | A new effect was discovered in welding thin metal plates with a low power CO2 laser. In the welding process, a small hole exists in the welding puddle and penetrates the plate. This effect was proved experimentally for the first time The conditions of power and energy density were also investigated experimentally and theoretically. |
