All cracks and planar defects are significant when considering the resistance of a welded structure to fracture and fatigue. These defects are the most likely initiation site for a brittle fracture, or for the propagation of a fatigue crack and, therefore, an understanding of the causes of possib...

Analysis on the Cause of the Defects of the Weld Seam in a Butt Welded Flange Ringdoi:10.1007/978-981-13-2173-3_18The causes of the crack formation were analyzed by macroscopic analysis, ultrasonic testing, chemical composition analysis, metallographic analysis, and energy spectrum analysis. The...
The characteristic features and principal causes of lack of sidewall and inter-run fusion are described. General guidelines on best practice are given so that welders can minimise the risk of imperfections during fabrication
However, they may sustain some additional loads due to ground movement or other external causes. Unlike factory-made welds, site welds cannot be fully stress relieved except in special circumstances. Often even site welds can be inspected for defects after they are completed, and in most cases ...
1. It analyzes 9 common defects causes and its prevent methods such as slag, pre-weld, uncompleted weld, forged weld, gas pocket and skip weld in the high frequency welded pipe production. 分析了高频焊管生产中夹杂物、预弧、熔合不足、边部熔合不足、中部熔合不足、粘焊、铸焊、气孔、跳焊等9...
Incomplete penetration is more harmful than porosity, slag inclusion, tungsten inclusion and other defects, which belongs to more harmful defects. 未焊透的原因 Causes of incomplete penetration 钝边过大,坡口角度小,选用的焊条直径过大,装配间隙小或边缘错边,使熔敷金属达不到根部。

This weld on this new auto part was so bad, I took this picture and hung it my office. I called this work of art "DIAARRHEA" The world's most overated process for steel welds has for decades been Pulsed MIG. A process that influences many lack of weld fusion defects: In the glo...
