Visual weld defects are defects in a weld that are only visible under certain conditions. They can help improve quality control and prevent future problems. See below for more information on visual weld defects.

What are visual weld defects?


Visual weld defects are small, unsightly flaws in the metal that is being welded together. They can occur when the welding process is not properly controlled, which can lead to the formation of bubbles and micro fractures in the metal. Visual weld defects can cause the weld to fail prematurely and potentially result in structural failure.


Causes of visual weld defects


Visual weld defects can be caused by a variety of factors, but they typically occur when the weld is too thin or when the weld is not properly aligned. If the weld is too thin, it can break and allow air to escape, which will cause a visual defect. If the weld is not properly aligned, the heat from the welding process can cause the metal to warp and form a visual defect.


Why they are so important?


Visual Weld Defects are incredibly important when welding because they can help us to identify potential problems early on in the welding process. By identifying weld defects before they become a problem, we can often prevent them from causing any damage or affecting the quality of our final product. Welders and fabricators must use the software correctly to produce quality products. Visual Weld defects can lead to major problems for companies that rely on it for their business. By understanding the importance of Visual Weld defects, companies can take steps to ensure that their products are safe and meet expectations.




Weld defects are one of the most common and costliest types of defects in metal fabrication. They can be caused by a variety of factors, including insufficient cooling during welding, incorrect filler material selection, and improper wire feed speeds. If left unchecked, visual weld defects can lead to joint failure, resulting in costly downtime and lost production. To prevent these losses, be sure to use the help of vision machines, such as MAKER-RAY‘s machine vision system, to help solve weld defects.
