葫芦门式起重机主梁焊缝检验及其质量评定

主梁不仅是葫芦门式起重机的主体部件,而且还是主要的受力构件,因此主梁的质量直接决定着整机的寿命,而主梁焊缝质量又是决定主梁这一焊接结构件的质量关键所在。所以从保证安全和质量的角度出发,对主梁焊缝的宏观和微观检验必不可少,且根据检验结果做出准确可信的质量评定是十分重要的。实践结果表明,在检验中不仅要按照标准的要求而且还要加以消化,才能把握好对主梁焊缝检验的尺度,直至给出正确的评定,进而达到保证起重机整机制造质量的目的。

The wilding seam inspection and quality assessment of the main beam of hoist gantry crane

The main beam is not only the main component of hoist gantry crane,but also the main force component,so the quality of the main beam directly determines the life of the whole machine,and the weld quality of main beam is the key that determines the quality of the welded structure of main beam.Therefore,to ensure the safety and quality,the micro and macro inspection to main beam is indispensable,and making accurate and reliable quality evaluation according to inspection results is very important.The practice ...
