🔧 Common Welding Defects – Causes & Prevention Visit weldfabworld.com Follow Technical Master Welding defects can seriously affect strength, safety, and service life of structures. Understanding their causes and preventive measures is essential for welders, inspectors, and QA/QC professionals. --- 🔹 1. Porosity 🧑‍🏭🧑‍🏭 Description: Small gas holes trapped in weld metal. Causes: Moisture, contamination, improper shielding gas. Prevention: Clean base material, dry electrodes, correct gas flow

Welding defects are irregularities or flaws that occur in a welded joint, which can affect the strength, durability, and overall quality of the weld. Here are some common types of welding defects: Visit weldfabworld.com Types of Welding Defects 1. *Porosity*: Small holes or pores in the weld metal, often caused by gas entrapment. 2. *Slag inclusions*: Trapped slag or flux in the weld metal, which can weaken the joint. 3. *Lack of fusion*: Incomplete melting of the base metal or previous weld pas
