Gas Welding Gas welding is a process in which acetylene and oxygen are used to produce a high-temperature flame zone to melt the material and fuse them to produce weld bead. Since there is no external filler material is used to produce weld pool so it is an autogenous process There are three types of flame produced duri…

Production of metallic powder All the property of powder metallurgy only depends on the size of the powder of metal/alloy when it is produced. the important characteristic of powder includes the size, shape and size distribution.   There are the following number of processes a used to manufacture the metallic powder- …

The terminology used in IC Engine Bore-  The inner diameter of the cylinder is known as the bore. Top dead center(TDC)-  The maximum displacement of the piston from the mean position is known as Top dead center. In this case, connecting rod and crankshaft are in the same line. When the top dead center is achieved…

Kaizen theory it is a Japanese theory in which slow but continuous improvement of system is the key principle. kaizen is the base of Lean manufacturing and Toyota manufacturing system.  In an Assembly line/work station that uses kaizen, all workers look for small ways to improve work processes in a regular manner. after …

Computer-aided manufacturing  It is the combination of computer and manufacturing process Based on that definition, you need three components for a CAM system to function: Software-  that tells a machine how to make a product by generating toolpaths. Machinery-  that can turn raw material into a finished product. Post Pr…

Water jet cutting operation It is the most versatile cutting process which can provide high precision cutting to any materials It uses ultra high-pressure fluid (water with a mixture of some abrasive(grits) to cut precision surface with smooth cut. It can produce very high tolerance cut. This process is very expensive comp…

Steady flow- When fluid properties of the system flowing through a control volume don't change concerning time then it is known as steady flow. Or, In steady flow Fluid, velocity will be constant at the different points at the same time. Unsteady flow- When fluid properties of the system(e.g.- pressure, temperature, d…
