摘要

PPROBLEM TO BE SOLVED: To provide a detection method capable of ensuring the soundness of a weld part by rapidly detecting acceptance/rejection (the volumetric ratio of vacancies in nugget, and the diameter of the nuggets) of a weld part to be formed by the spot welding in a non-destructive manner, and a detection device useful therefor. PSOLUTION: The detection device includes: a gas collector 3 connected to a collection hole for collecting CO gas and/or COSB2/SBgas generated around a weld part during the spot welding; a gas analyzer 4 for measuring the amount of CO gas and/or COSB2/SBgas collected in the gas collector 3; and an electronic computer 7 for processing the data of the amount of the measured gas. The electronic computer 7 determines the volumetric ratio of vacancies according to the relationship grasped in advance. PCOPYRIGHT: (C)2011,JPO&INPIT

要解决的问题：提供一种检测方法，该方法能够通过快速检测待焊接零件的合格/不合格（熔核中空位的体积比和熔核的直径）来确保焊接零件的健全性。通过非破坏性的点焊形成的检测装置以及有用的检测装置。

解决方案：该检测装置包括：集气器3，其连接到用于在点焊期间在焊接部分周围产生的CO气体和/或CO 2 气体的收集孔;以及气体分析器4，用于测量收集在气体收集器3中的CO气体和/或CO 2 气体的量;电子计算机7，用于处理测定气体量的数据。电子计算机7根据预先掌握的关系来确定空位的体积比。
