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
