454c8 01 gas porosity in castings Casting Quality Test Methods Non Destructive Testing And Destructive Testing Methods NDT Testing

Interpretation of Casting Radiographs Castings are made of different metals and by various methods. Sand molded castings often have more surface irregularities than casting produced by metal mold and investment methods. Knowledge of various casting processes and casting defects helps effective radiographic evaluation. The major defects in castings and weldments are given below: 1. Gas porosity become visible as round

What Is Fuel Cell Technology | Fuel Cells Pros And Cons

Introduction to Fuel Cell A fuel cell is an electrochemical mechanism that produces power without combustion by joining hydrogen and oxygen to generate water and heat. The voltage created by a single cell is typically rather small (< 1 volt), so many cells are connected in series to create a useful voltage. Hydrogen fuel cells are feasible to modernize the

b7bba 01 ultrasonic welding process how to weld plastic Manufacturing Engineering Ultrasonic Welding

Making of Ultrasonic Weld: Although the theoretical method of manufacturing an ultrasonic weld is uncomplicated, the interactions of the varied weld parameters are vital and may be understood. When manufacturing an ultrasonic weld, there are 3 primary variables that interact; They are: • TIME the period of applied ultrasonic vibration • AMPLITUDE the longitudinal displacement of the vibration • FORCE

Ultrasonic Welding: Ultrasonic welding is represented as a friction welding method, where oxides and other contaminants present on the material surfaces are broken up and also the components to be welded are brought together under simultaneous pressure. Molecular bonding, just like the conventional cold-press welding, then takes place. Ultrasonic welding is the conversion of high frequency electrical energy into high

Ultrasonic Welding: The human ear can hear mechanical vibrations in the frequency range of 16 Hz to 16 KHz. Inaudible frequencies below 16 Hz are known as infrasound and those between 16 KHz and 100 GHz are known as ultrasound. Frequencies above 100 GHZ are known as hyper sound. The process is “green” in that it does not use solvents,

BEARINGS A bearing is a machine element that constrains relative motion between moving parts to only give the desired motion. The design of bearing may be provide for free linear movement of the moving parts or free rotation around a fixed axis or it may prevent motion by controlling the vectors of normal forces that bear on the moving parts

Speed Governor The governor is a device which is used to controlling the speed of an engine based on the load requirements. Basic governors sense speed and sometimes load of a prime mover and adjust the energy source to maintain the desired level. So it’s simply mentioned as a device giving automatic control (either pressure or temperature) or limitation of
