摘要
Abstract
The effect of fluoride(sodium fluoride NaF and lithium fluoride LiF)ratio in the flux core on the welding perfor-mance of E308LT1-1 stainless steel flux-cored wire was systematically investigated.Five types of wires with different NaF/LiF ratios were designed.The droplet transfer behavior,welding spatter,weld oxidation color,and slag microstructure were analyzed by means of high-speed photography,scanning electron microscopy,ICP,and X-ray fluorescence spectrometry.The results indicated that fluorides regulated the welding performance by influencing arc stability,droplet force state,and the physicochemical properties of the slag.When the mass ratio of NaF to LiF in the flux core was 3:1,the spatter rate reached its minimum value of 3.34%.Increasing the LiF proportion contributed to improving the weld oxidation color but re-duced arc stability and vertical-up welding operability.When the NaF-to-LiF ratio was 1:1,the wire exhibited optimal over-all welding performance.关键词
