Fettling and Heat treatment of castings, Casting defect and

This course provides a practical understanding of fettling and heat treatment processes used for improving the quality and performance of castings. Participants learn how to remove gates, risers, fins, excess metal, and other unwanted material from cast components. The course explains common fettling tools, equipment, and safe working practices used in foundries. It covers different heat treatment methods used to improve the strength, hardness, toughness, and machinability of castings. Participants also learn about common casting defects such as cracks, porosity, blowholes, shrinkage, inclusions, and misruns. The course explains how defects are identified through visual inspection and other diagnostic techniques. Different testing and inspection methods are introduced to help find the causes of casting defects. Participants learn how process conditions, moulding, melting, pouring, and cooling can contribute to defects. The course also focuses on corrective actions and methods for reducing recurring casting problems. Overall, it helps participants improve casting quality, production efficiency, and safe foundry practices.
