铜及铜合金管的通常工艺是热挤压,然后在皮尔格(Pilger)轧机上轧制减径,最后拉拔成成品。最近,对Cu—Ni管的高频感应焊接研究所得的结果表明,焊接铜及铜合金带以生产管材是有前途的。使用了五种材料:商业纯铜、磷脱氧铜,铜—30锌、铜— The usual process for copper and copper alloy tubes is hot extrusion followed by rolling reduction on a Pilger and finally drawing into finished product. Recently, the results of RF induction welding of Cu-Ni tubes show that welding of copper and copper alloy ribbons is promising for pipe production. Five materials were used: commercial pure copper, phosphorus deoxidized copper, copper-30 zinc, copper-
