简介：当听到“我们需要改善焊缝质量”这句话时，你通常联想到的是：需要做更多的检查，因此需要雇佣更多的人；提高质量很可能降低产能，增加成本和花费更多时间；

简介：轴承在运行159min时出现异常，拆解后检查发现1粒滚珠表面存在裂纹，内圈、外圈等处未见明显异常。通过对滚珠外观进行观察，对裂纹断口进行宏微观观察、能谱分析、材料显微组织、硬度等进行检测分析，确定了失效性质，并对其失效原因进行了分析。结果表明：故障滚珠失效性质为疲劳开裂；原材料铸造孔洞缺陷在后续加工过程中被拉长、压扁而保存下来，并以微裂纹形式存在于钢材内部成为疲劳源，最终导致了疲劳失效，该孔洞缺陷是在电渣熔炼过程中形成且后续未被切除干净的残余缩孔。
