摘要
为生产厚壁不锈钢焊管，采用W孔型并对成型部分的孔型进行改进，可避免带钢在成型焊接过程中产生“噘嘴”和划伤现象，使成型过程稳定，产品焊接质量和外观质量良好。介绍了该孔型的设计方法。
By means of W groove with the formation section modified,it can be done to prevent the strip from being displaced and scratched during welding formation process in manufacturing heavy-wall stainless steel weld pipe. In addition,the formation operation will be very consistent and the welding quality and visual quality of the pipe will be very good. This groove design method is detailed in the paper.
