The low production efficiency and large welding deformation of traditional clad pipe are improved. The mechanical properties and corrosion resistance tests results show that the clad pipe formed by automatic hot-wire TIG surfacing has excellent mechanical properties and corrosion resistance. This process can provide technical reference for the optimization of the manufacturing of the clad pipe for oil and gas transportation. 堆焊 复合管 825合金 热丝TIG焊 surfacing clad pipe 825 alloy hot-wire TIG welding TE973.3 2022-03-08 11 51
