摘要
分析了焊缝余高、焊缝宽度、焊缝过渡角、焊缝均匀性等焊缝外观形状的主要几何参数及其控制要求,并通过对钢管螺旋缝焊接和焊缝成型特点的分析,阐明了焊缝外观形状控制的难点。指出了焊缝外观形状常见问题的产生原因和防止措施,对生产实践有一定的指导意义。
It analyzes appearance shape of weld of weld reinforcement,width,transitional angle and uniformity,etc..,main geometry parameter and its control requirements.It illustrates difficulty of weld appearance shape control through analysis of welding and characteristic of weld forming.It points out that occurring reason and prevention measures of ordinary weld visual shape problem to guide the production practice.
