Welding is a process for joining two similar or dissimilar metals by fusion. It joins differentmetals/alloys, with or without the application of pressure and with or without the use of fillermetal. The fusion of metal takes place by means of heat. The heat may be generated eitherfrom combustion of gases, electric arc, electric resistance or by chemical reaction.Welding provides a permanent joint
