Gas Welding Process: Definition, Equipment, Working Principle, Types of Flames, Advantages, Disadvantages & Applications [PDF]

To speak simple, Gas welding is a process of joining two metals with the application of heat from the flames so that they will melt and join together. In the last session, we had discussed Electric Arc Welding process along with Arc Recovery Time and Arc Characteristics whereas, in today's session, we can discuss Gas […]

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 […]

Types of Plastics-Properties of Thermosetting Plastics & Thermoplastics [PDF]

In this article, I will be explaining the different types of Plastics used in our household applications as well as industrial applications in the form of Thermoplastics and Thermosetting Plastics with there Properties. but before that let we know what is a Plastic? Plastics:  Plastics are also called as Polymers. They are made up of carbon, hydrogen […]
