摘要
This invention regards laser beam welding process and the equipment which utilize the sealed gas blend which includes argon and helium. The argon in the aforementioned gas blend and/or ratio of helium, following to output of the laser beam or output density, is selected or adjusts and. Laser output 0.5kW or 30kW and to be desirable is included in 5kW or 20kW. That sealed gas blend includes argon and/or helium, desirably, that gas blend includes the helium of 30% or 80% specific volume, the remainder argon and is the inevitable impurity which can exist.
