What is Undercut in Welding (Causes & Possible Remedies)

undercut in welding

An undercut is a surface and subsurface defect resulting from grooves within the parent metal area. Like all other defects, instead of improving the joint strength, it introduces weak points that often propagate structural failure. At the microscale level, the micro-cracks are observed within the defective surface, meaning material failure is inevitable if not remedied […]

What is Slag in Welding, and How Does It Work?

solidified slag

Slag in welding can be defined as “stony waste that is separated from metals during the smelting or refining of ore.” While we are not dealing with ore when we are welding, welding slag is also separated from the base and filler metals during welding. It is then chipped off and cleaned up later on. […]
