摘要
对塞尔维亚奥布雷诺瓦茨(Obrenovac)尼古拉特斯拉A (Nikola Tesla A)火电厂堆煤堆中斗轮挖掘机臂架(DU1)焊接结构关键部件的损坏原因进行了研究。斗轮挖掘机是由法国Ameco公司生产的，它沿着圆形轨道移动。考虑到缺乏技术文件，所有的测试都是在假设焊接结构由S355和S235结构钢制成的情况下进行的。损伤发生的原因调查是基于无损检测(NDT)和张力测量的结果。
Damage Occurrence in Welded Structures of the Bucket-Wheel Boom
Causes of damage occurrence in vital components of welded structures of the bucket-wheel excavator boom (DU1) at the coal landfill of the thermal power plant 'Nikola Tesla A' in Obrenovac (Serbia) are investigated. Bucket-wheel excavator was produced by French company 'Ameco' and it moves along the circular track. Taking into account lack of technical documentation, all tests and were carried out under the assumption that welded structures were made of structural steels S355 and S235. Investigation of causes of damage occurrence are based on results of non-destructive tests (NDT) and tensometric measurements.
