There are many different types of weld defects that can occur during the welding process. Here is a list of some common weld defects:

Incomplete fusion: This occurs when the weld metal does not fully fuse with the base metal or previous weld passes. This can result in a weak weld and potential failure.
Porosity: This is a type of gas defect…
