本文探讨了薄板焊缝用焊缝宽度法探伤的特点和避免漏检的各种条件,讨论了探头参数的选择原则,并指出理想焊缝扫查声程应限制在0.75～1.1N区域。本文试图在理论和实践的基础上完善这一方法。
In this paper, the characteristics of the flaw detection by the weld width method and the various conditions for avoiding the missed inspection are discussed. The principle of selection of the probe parameters is discussed. It is pointed out that the ideal sounding path of the weld should be limited to the range of 0.75 ~ 1.1N. This article attempts to perfect this method on the basis of theory and practice.
