What is Lack of Fusion (LOF) in Welding & How to Prevent It?
Welding is the backbone of modern fabrication and construction. Whether it is pressure vessels, pipelines, bridges, or structural components, weld quality directly determines safety and reliability. Among all welding defects, Lack of Fusion (LOF) — also known as Incomplete Fusion — is one of the most critical because it compromises both strength and integrity of […]
