Structure and Properties of Engineering Materials The existence of solids in nature occurs principally in two forms:  crystalline  non-crystalline (amorphous) Crystals   are solids that possess long-range order. There is a long-range order in crystalline solids, a regular pattern of arrangement of particles that repeats itself periodically can be seen over the whole crystal. Excluding the defects that can arise during the crystal growth, the arrangement of the atoms at one point in a crystal is identical to that in any other part of the crystal. Determination of the number of ways in which the component atoms are arranged in crystals and how the long-range order may be achieved is done using crystallography.  Many physical and chemical properties are dependent on crystal structure and therefore the knowledge of crystallography is necessary if the properties of materials are to be understood and exploited. Space Lattices-     A space lattice provides the framework with reference to whic

Car Parts names & their functions A car is made up of several component parts that work together to deliver power and eventual mobility to the car. In this article, we will discuss the basic parts of a car and their individual functions.  First, let's have an overview of the parts of a car below.

  TYPES OF WELDING JOINTS What is Welding Joint? Welding is a process that needs patience, detail, and creativity. To perform it successfully, welders should have an understandable knowledge of the various methods and practices used in the industry, also including types of welding joints. A welding joint is referred to an arrangement or configuration of two metal plates that will be fit together. The purposes of welding are infinite, and different processes require different types of welds and joints. According to the American Welding Society (AWS), there are 5 basic additions that are commonly known and applied. These welding joint types are each stands for the needs and forces of different applications. So, let’s discuss them one by one. Types of Welding Joints Following are the 5 main types of welding joints: Butt joint welding Lap joint welding Edge joint welding Tee joint welding Corner joint welding 1. Butt Joint Welding These types of welding joints form when the two metal piece
