Introduction Chemical Machining Process (CHM) In chemical energy methods, Chemical Machining Process the metal is removed from the workpiece through controlled etching of the workpiece material in contact with a chemical solution. Example: Chemical Matching (CHM) In Electro chemical energy methods, material is removed by ion displacement of the workpiece material in contact with a

Solid state welding is a group of welding processes which produces coalescence at temperature below the melting point of base materials being welded without the addition of brazing filler metal. Metallurgical bond is created without melting the base metals.  In this welding, heat may or may not be applied. These processes are sometimes called solid

Types of Welding Fundamental principles, types of welding, Air Acetylene welding, Oxyacetylene welding, carbon arc welding, shielded metal arc welding, submerged arc welding, TIG & MIG welding. 1.Gas welding: (a) Air-acetylene welding (b) Oxy-acetylene welding (c) Oxy-hydrogen welding. 2. Arc welding: (a) Carbon arc welding (b) Plasma arc welding (c) Shield metal arc welding (d)

INTRODUCTION TO WELDING PROCESS The process of joining similar metals by the application of heat is called ‘welding’. It is a fabrication process that joins materials, usually metals or thermoplastics, by causing coalescence. It is often done by melting the workpieces and adding a filler material to form a pool of molten material that cools

Introduction Mechanical Energy – Machining Process In mechanical energy methods, the material is removed by mechanical erosion of the workpiece material. Examples :  Abrasive Jet Machining (AJM)  Water Jet Machining (WJM)  Ultrasonic Machining (USM) ABRASIVE JET MACHINING (AJM) – Mechanical Energy In abrasive jet machining process, a high speed stream of abrasive particles mixed with

CONVENTIONAL MACHINING PROCESS In conventional machining process, metal is removed by using some sort of tool which is harder than the work piece and it is subjected to wear. In this process, tool and work piece are in direct contact with each other. In other words, the conventional machining process involve removal of metal by
