Study on Welding Process of Crack-arrest Steel Using a Portable Autonomous Welding Robot
摘要
Abstract
A portable fully automatic welding robot is employed to weld E40BCA1COD and E47BCA1COD crack-arrest steels.By adjusting heat input process parameters,the effects of heat input variation during robotic welding on the mechanical performance of crack-arrest steel weld joints are investigated,and an optimized welding procedure is established.The results demonstrate that the robotic system achieves autonomous welding of crack-arrest steels without manual intervention.With fewer human-dependent factors,the welding stability is significantly enhanced.Comparative tests under different heat inputs revealed that compared to the conventional process with a maximum heat input of 27 kJ/cm,the proposed process with 35 kJ/cm heat input reduced the number of weld passes by 30%~40%under identical plate thickness conditions,while improving welding efficiency by over 25%compared to traditional methods.The optimized process demonstrates promising application potential in welding crack-arrest steels for structural components such as hatch coamings and torsion box structures in large container ships,effectively enhancing productivity,ensuring weld quality,and reducing post-weld rework requirements.关键词
