| Research Abstract |
The welding characteristics and evaluation of molten zone were investigated in order to realize the high reliable micro-joining process of glass material by ultra-short pulsed laser. Molten zones created by the ultra-short pulsed laser in a glass material were experimentally investigated. The laser scanning speed influenced the molten zone size of glass welding, while the pulse repetition rate had the direct influence on the generation of crack and micro bubble. The strength of molten zone was almost equal to the base material, and high strength could be obtained at the low velocity and the high pulse repetition rate condition.
