Abstract
Due to the traditional cleaning technology to deal with high-strength welding wire,there are unavoidable prob-lems such as heavy workload and serious pollution.In this paper,laser-cleaning technology is used to clean the surface of high-strength welding wire.The effects of cleaning-times,laser power and scanning speed on cleaning rate,surface rough-ness and element distribution were studied.The results show that when the cleaning-times N equals 6,there is an uncleaned rust layer on the surface of the welding wire;when N equals 10,the corrosion layer is basically cleared,but the heat input is too large,and the substrate is oxidized and ablated under the action of laser,so that the surface is light brown.When N equals 8,the corrosion layer is basically cleared,and the surface is bright white metal luster.The surface roughness is af-fected by the scanning speed and laser power.The roughness is proportional to the laser power and inversely proportional to the scanning speed.When the laser power P equals 12 W and the scanning speed v equals 1 200 mm/s,the roughness is the smallest,Ra equals 2.07.When the laser power P equals 20 W and the scanning speed v equals 800 mm/s,the roughness is the largest,Ra=6.64.By comparing the content of oxygen before and after laser cleaning,it can be obtained that when the laser power P equals 16 W and the scanning speed v equals 1 200 mm/s,the lowest oxygen content is 3.9 wt.%,which is 84.08%lower than that before cleaning.Based on the three indexes of rust removal rate,roughness and element content,the laser cleaning-times N=8,laser power P=16W,scanning speed v=1 200 mm/s were selected as the optimal process pa-rameters.Under this process parameters,the rust removal rate is 95.8%;the surface roughness is Ra=2.52,the oxygen con-tent is 3.9 wt.%.关键词
