焊接参数对镁合金焊接等离子体电子温度的影响

In the previous work, spectra information of welding plasmas in TIG welding and hybrid welding processes is acquired and the electron temperature of welding plasma is estimated by. Based on this, the effect of welding parameters, such as arc current, welding speed, laser power and so on, on the electron temperature of welding plasmas are studied in this article. In addition, the reason that welding parameters induce the variations of electron temperature of welding plasma is analyzed, which supplies experimental basis for directing practical welding process, founding quality-control system of laser/arc hybrid welding process and perfecting laser/arc hybrid welding theory.
