Top 10 Welding Defects and What Causes Them
Welding is a process that may seem easy from a distance. Sparks fly off as metal is melted, and two parts are brought together. However, as a welder gets into a workshop, things are not as smooth as they seem. Small mistakes can quickly lead to welding defects. These defects may cause a weld to become weaker or cause more problems when it is put to use again. Welders are taught not only to weld but also to identify defects that may occur during a weld. In a busy place like Engineering Toowoomba , where machines and parts are manufactured for use under pressure, weld quality is very important. Here are ten common defects that may occur during a weld and why they may happen. 1. Porosity Porosity is a weld that has holes inside it. This occurs when there is a buildup of gas inside a weld. The buildup occurs when metal surfaces are dirty, or there is moisture or rust on the metal. 2. Lack of Fusion This is a weld that has developed a defect as a result of a lack of fusi...
