It is the mother of all manufacturing and deals with moulds, jigs & fixtures, plastics, die casting, dies and so on. A student who did this course from igtr aurangabad. Across manufacturing sectors you begin as a technician. Quite a few tool and die makers become tool designers. Some open their own tool and die shops.

Welding is a fabrication or sculptural process that joins materials, by causing coalescence. This is often done by melting the work pieces 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 work pieces to form a bond between them, without melting the work pieces.

X-ray Welding is an experimental welding process that uses a high powered X-ray source to provide thermal energy required to weld materials.

X-ray welding also has a somewhat archaic quality control application. In this context, an X-Ray welder is a tradesman who consistently welds at such a high proficiency that he rarely introduces defects into the weld pool, and is able to recognize and correct defects in the weld pool, during the welding process. It is assumed (or trusted) by the Quality Control Department of a fabrication or manufacturing shop that the welding work performed by an X-ray welder would pass an X-ray inspection. For example, defects like porosity, concavities, cracks, cold laps, slag and tungsten inclusions, lack of fusion & penetration, etc., are rarely seen in a radiographic X-ray inspection of a weldment performed by an X-ray welder.
