High Frequency Induction Welding of Tube Pipe Under Cold Roll Forming Process: Review
摘要
High frequency induction weld pipes are making significant contributions by replacing seamless pipes for the transmission of pressurized water, oil, and gas. Pipes are made from strip sheet, which is first shaped into an open tube using progressively arranged roll forming, and then the open edge is closed with continuous longitudinal seam welding using a high frequency induction welding machine. The ultimate quality of the pipe is determined by the combined effects of the sheet metal roll forming and welding process parameters, which have varied mechanical properties. The main reason for mechanical property variation is the difference in residual stress caused by roll forming redundant deformation and the welding process thermal heat fluctuation. Properly selecting roll forming parameters helps to prevent buckling faults that hinder the welding process; additionally, heat input parameters and the squeezing roller pressure play a vital role for the mechanical properties of longitudinal welded pipe. This work provides a complete assessment of available numerical and experimental studies on high frequency induction welding of tubular pipes under roll forming procedures. As a result, more research is needed on optimizing the mechanical, electromagnetic, and welding temperatures of the tube manufacturing process for free residual stresses generated by pipe roll forming and high frequency induction welding processes.
