闪光对焊工艺对耐蚀螺纹钢HRB400M焊接接头组织和性能的影响
Effect of flash butt welding parameters on microstructure and property of weld joints of corrosion resistant rebar HRB400M
摘要
Abstract
Flash butt welding was applied to corrosion-resistant rebar HRB400M with a diameter of 25 mm,and microstructure and property of the welded joints were investigated.The optimum welding parameter includes out of fixture length of 21 mm,flash heat output of 68 kW,flash speed of 0.8 mm/s,flash allowance distance of 12 mm,electric upsetting time of 0.1 s,upseuing pressure of 65 MPa,along with preheating and post-weld tempering process.The ferrite area on both sides of the welded joint center line is the weakest part,which can be eliminated by adjustment of welding parameters.关键词
