How are grating manufactured?
Electric welding, also known as electro-forged, is a thermoelectric process in which heat is generated by the passage of electric current. During the process, metal parts (commonly steel) are pressed together by the welding machine”™s electrodes to assure a firm and constant electrical contact. …
How is grating made?
A diffraction grating is made by making many parallel scratches on the surface of a flat piece of transparent material. It is possible to put a large number of scratches per centimeter on the material, e.g., the grating to be used has 6,000 lines/cm on it. A parallel bundle of rays falls on the grating.
