education system is one of the basic requirement for any country.In Bangladesh it was first introduced by one of the greatest education specialist named Dr. Kudat-e-Khuda .It was introduced when Bangladesh just write her name in world map,as a new born baby country,in 1972.though the principal was not able to implemented properly.day by day that should be changed,perhaps that not happen.Now it is burning question to make introduce an unique new education system.Education needs to change itself.that should be liberal.But in case of education system that should have an unique vision,direction.so that it empower itself according to it's desecration.it is Welding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics, by causing coalescence. This is often done by melting the workpieces and adding a filler material to form a pool of molten material (the weld pool) that cools to become a strong joint, with pressure sometimes used in conjunction with heat, or by itself, to produce the weld. This is in contrast with soldering and brazing, which involve melting a lower-melting-point material between the workpieces to form a bond between them, without melting the workpieces.

Many different energy sources can be used for welding, including a gas flame, an electric arc, a laser, an electron beam, friction, and ultrasound. While often an industrial process, welding may be performed in many different environments, including open air, under water and in outer space. Welding is a potentially hazardous undertaking and precautions are required to avoid burns, electric shock, vision damage, inhalation of poisonous gases and fumes, and exposure to intense ultraviolet radiation.
