摘要
简要分析了带钢在成型为待焊开口管坯的变形过程中，其边缘鼓包的形成机理。阐述了绝大部分鼓包都是材料、孔型、轧制线、设备、操作等因素综合作用引起的。
The writer briefly analyses the mechanism of edge bulging of the strip being formed into blanks to be welded and makes the point that in most cases the said bulging is deve loped due to a combined effect by such factors as material,groove,passing line,equjpment and operation.Some countermeasures against bulging are also proposed here.
