Inclusion in welding
WebTungsten inclusions: In the TIG process, the touching of the electrode to the weld metal may cause transfer of the tungsten particles into the weld metal. These inclusions are detected by x-ray and show up as bright particles since they are much denser than the steel. An example is shown below where the x-ray revealed the tungsten inclusions. WebMar 26, 2016 · Welding For Dummies. Incomplete fusion is a lack of penetration or fusion between the weld metal and the parent metal of the piece. Welds with incomplete fusion are weak and substandard welds at best (if not downright dangerous). Here are a few of the most common causes for incomplete fusion, and solutions that will help you avoid the …
