Introdution The hole drilled by the drilling operation is rough on the inside and not as accurate as required. Also, for the perfect fitting, accuracy, and finishing of the hole is most important. Therefore, a process is required that provides a fine finishing surface to the hole and ensures the hole is more accurate. That … Read more
Introduction Solid state welding techniques have ushered in a transformative era in modern manufacturing, revolutionizing conventional joining processes. This innovative approach has disrupted traditional methods, offering unparalleled benefits across various industries. Solid State Welding Techniques Revolutionizing Modern Joining Processes Welding has long been a crucial aspect of various industries, serving as the backbone for joining … Read more
Introduction Welding is the art of joining materials. It is a fabrication or sculptural process that joins the materials, usually metals or thermoplastics, by causing coalescence. Normally, in welding operations, the joining of metal pieces is done by raising their temperature to the fusion point so that they form a pool of molten metal that … Read more
Soldering and brazing are the processes of joining similar or dissimilar metals. There are three processes of joining the metals i.e., soldering, brazing, and welding. The major difference between them is that a huge amount of heat is required in the case of welding, a low amount of heat is needed in the case of … Read more
It is the simplest and most accurate machine, which is used in production shops. The workpiece is held stationary i.e., clamped in position and the drill rotates to make a hole. It is designed specifically to operate drilling and similar operations. Drilling machines are classified based on their constructional features and the types of work … Read more
Drilling is an operation through which holes are produced in a metallic or non-metallic material through a revolving tool called a drill. The whole process is carried out on a specific machine known as a drilling machine. The machine provides rotatory motion to the drill and is directed toward the workpiece where the hole is … Read more
Sheet Metal nowadays, we are using many such things in our daily lives, which are made from metal sheets, such as boxes, tanks, trays, etc. It is one of the fundamental forms used in metalworking, and it can be cut and bent into different shapes. Sheet metal work can be done with metals such as … Read more
Sometimes, it is necessary to mold metal into a desirable shape. To obtain this shape, a certain amount of heat must be given to the metal. This heat converts a solid metal into a plastic one. The process of converting the solid metal into the desired shape by heating is known as the heat treatment … Read more
Forging is one of the oldest methods to produce the required shape from the red-hot metal. Generally, hammers are used for shaping the parts of an object. Forgings can be defined as the controlled plastic deformation of a metal at elevated temperature into a predetermined size or shape by using compressive forces. Forgings may be … Read more
In engineering fields, metals have great importance because of every smallest part, and big machines are normally made up of metal. i.e., from the manufacturing of a needle to a big ship, metal is used. Metal is a kind of mineral substance, which is obtained from mines after cleaning the raw materials. This raw material … Read more
