WELDING AND FABRIGATION OF branding iron ROD WELDING AND guile OF IRON ROD Methods involving in conjoin. Welding, in engineering, any appendage in which devil or more pieces of metal ar fall in to pull inher by the application of warmth, compact, or a conclave of both. Most of the processes may be sorted into two chief(prenominal) categories: insisting conjoin, in which the weld is achieved by pressure; and heat welding, in which the weld is achieved by heat. Heat welding is the closely common welding process used straight off. Brazing and soldering (see solder) are different means of joining metals.

Along with soldering and brazing, it is essential in the harvestingion of virtually both manufactured product involving metals. The welding process best meet to joining two pieces of metal depends on the physical properties of the metals, the particular use to which they are applied, and the production facilities available.

Welding processes are in general classified match to the sources of heat and pressure used. The original pressure process was work on welding. Forge welding was exercise for centuries by blacksmiths and other artisans. The metals are brought to a suitable temperature in a furnace, and the weld is achieved by hammeri ng or other mechanical pressure. Forge weldi! ng is used rarely in modern manufacturing. The welding processes nearly commonly employed today include gas welding, electric discharge welding, and resistance welding. new(prenominal) joining processes include thermite welding, laser welding, and electron-beam welding.
