摘　　要：用Stark展宽光谱法分别对激光、TIG焊电弧以及激光加TIG焊电弧的电子密度进行测定.发现电弧强化激光焊机理在于电弧有稀释激光等离子体的作用。明显降低了激光等离子体对激光能量的吸收和反射,提高了激光束的热加工效率.试验研究表明,激光焊加电弧的作用,可以显著提高激光束的穿透能力.The electron density of laser, TIG welding arc, and laser+TIG welding arc plasma are measured by the method of Stark Broadened Linewidth. The reason why electric arc enhances laser welding is that the electric arc can dilute the electron density of laser plasma, weaken the ability of laser plasma to absorb and reflect the laser energy, and improve the hot-working efficiency of laser beams. Experiments prove that the combined action of arc and laser beams can obviously improve the weld penetration in welding.
