Brazing and Soldering Process: Working, Advantages, Disadvantages & Applications [PDF]

In all the non-fusion welding processes, when the liquid molten metal is poured at the joint, it gets wet and Solidifies. During the process of Solidification, the atoms present on the surface of the filler rod are sharing the energy with atoms present on the surface of parent material, and thereby it produces the joint. When the surface […]

Casting: Definition, Types, Steps involved in casting, Advantages, Disadvantages, Importance [PDF]

Definition of Casting: Casting is a process in which the liquid molten metal is poured into the casting cavity whose shape is same as that of the shape of the casting to be produced, allowing to solidify and after solidification, the casting will be taken out by breaking the mould called as Casting Process. Types […]

Sand Casting Process: Definition, Terminology, Explanation, Advantages, Disadvantages & Applications [PDF]

The sand casting process is used for the creation of cylinder blocks, machine tool beds, pistons, etc. where you can produce the components in bulk which is not possible by means of the machining process. All the beds of machines are large enough and cannot be prepared on any machine. Therefore, those products will be […]
