[English] Lack of Fusion (LOF) in Welding

This video explains about a welding defect known as Lack of fusion (LOF/LF) which is also called as "Incomplete fusion". Lack of fusion is a very dangerous welding defect and unacceptable in many codes and standards in the world. Different types of lack of fusion, their causes and remedies discussed in this video.
