Abstract

A 17 mm lowcarbon steel plate is welded by a fiber laser with a narrow gap joint configuration and multipass technique A highspeed camera is used to realtime monitor the welding process and the effects of groove size and the side shielding gas on the weld quality are studied Experimental results showed that a concave shape in the bottom of weld can be formed when use a general shielding gas nozzle with the 80 mm external diameter Through a special design of the shielding gas nozzle with the 20 mm external diameter which can deep into the interior of groove the pressure from shielding gas can balance the surface tension from the liquid in the top of groove so the shielding effect can be dramatically improved and the concave shape in the bottom of weld can be eliminated When the filler wire and laser beam can smoothly enter the groove using a relatively small groove size not only reduce the consumption of filler wire but also reduce the deflection of filler wire in the gap that can improve the fusion of grooveYangchun Yu received his PhD degree in Material Processing Engineering from Huazhong University of Science and Technology HUST China in 2010 He is currently working in Nanchang Institute of Technology from 2011 His research interests main in laser materials processing and welding materialsChunming Wang is an associate professor at the School of Materials Science and Engineering Huazhong University of Science and Technology HUST China His research interest is laser materials processing At least 20 of his papers have already published
