Diagram butt welding:- 


Explanation: Transformer used for welding is designed for low voltage and high current secondary. Transformer is oil cooled The job is clamped as shown in fig. two parts which are to be welded are brought together Sufficiently heavy current is passed through joints by welding transformer, which creates necessary heat at joints due to I2R When welding temperature is reached supply is cut down. And external pressure is applied simultaneously across the job to complete weld
