Introduction To Welding Pdf Welding Construction Welding introduction: welding is the metallurgical process of joining two pieces of metals by the application of heat and with or without the application of pressure and filler material. applications of welding: the chief application of welding is in making bridges and buildings. Welding is a process that joins two metal pieces by heating them to melting point and allowing them to fuse together. the main welding processes are electric arc, gas, thermit, resistance, and friction welding. proper surface preparation and use of fluxes is important to remove impurities and oxides.
