Working of Electrical Arc Welding
In electric arc welding electrical energy is converted into heat energy. Electric arc welding is based on the principle that, when electric current is passed through the circuit, gases present between air gap (small gap between electrode and workpiece) ionized and opposite polarity particles collides with high acceleration which generate high intensity of heat and energy (arc) this energy produced are used to weld metals.
Due to heat developed both electrode and base metal get melted. The electrode and workpiece brought nearer with small air gap of below 3mm approximately and Arc temperature between two metals is approximately 4000 degrees Celsius.
Length of air gap (distance between electrode tip and workpiece) between electrode and workpiece is lies between 3mm to 6mm.
Electric arc welding works on very high temperature (about 3700 to 4500 degrees Celsius)., and the metal in contact with the arc becomes molten which enables a weld to be melt.
Electric Arc Welding
Welding is an operation whereby two or more metal parts are joined by means of heat or pressure or both. Generally, only heat generation is required in welding but sometimes both heat and pressure are required to weld metal parts.
