What is Brazing? Basically, brazing, welding, soldering all are quite similar metal joining processes. There are some little bit differences which compel us to give different names to this metal joining processes. In this article we will discuss what is brazing, why brazing is different from soldering and welding, why to select brazing and not …
As you all know soldering is a process of joining two or more metals or two dissimilar items by melting and putting a filler metal (solder) into the joint and this filler metal have lower melting point than the base metal. Soldering requires practice, skills and some perfect knowledge for doing it. In this article, …
What is Soldering? In this article you will know what is soldering, various processes involved in soldering. Soldering is a process of joining two or more metal pieces by melting and then filling the joint by a solder. Solder and a flux are the two important things required during soldering. Soldering has a wide range …
Introduction Coal may be black in color but it light’s up about 60% of our country. Coal has been a reliable source of energy for India from years. About 72% of the total coal extracted, goes into generating electricity in coal power plant and it is available in abundance at different locations of India. It …
The pattern is the replica of the device which is the output of the casting process. This when molded in sand forms mold. After filling the mold with the molten metal there is a formation of casting. Patterns play a very important role in casting as they decide the quality as well as perfection in …
During the casting of metals in the foundry shop we use sand for the preparation of mould. It is the moulding sand properties which improves the quality of the casting metal. If sand of suitable property is chosen, then it greatly minimises the casting defects that may be produced during the mould preparation and casting. …
What is Casting Defects? It is an unwanted irregularities that appear in the casting during metal casting process. There is various reason or sources which is responsible for the defects in the cast metal. Here in this section we will discuss all the major types of casting defects. Some of the defects produced may be …

Water Jet Machining (WJM) also called water jet cutting, is a non-traditional machining process in which high-velocity jet of water is used to remove materials from the surface of the workpiece. WJM can be used to cut softer materials like plastic, rubber or wood. In order to cut harder materials like metals or granite, an …

Electrochemical machining (ECM) is a machining process in which electrochemical process is used to remove materials from the workpiece. In the process, workpiece is taken as anode and tool is taken as cathode. The two electrodes workpiece and tool is immersed in an electrolyte (such as NaCl). When the voltage is applied across the two …
Ultrasonic Machining (USM) also called as ultrasonic vibration machining is a machining process in which material is removed from the surface of a part by low amplitude and high frequency vibration of a tool against surface of material in the presence of abrasive particles. The motion of the tool takes place vertically or orthogonal to …
