Abstract

The microstructure formed on the surface of API 5L X65 steel conducted underwater water wet welding is influenced by the surrounding environment and the selection of electrodes used. E6013 electrode coated with polyester resin was chosen to prove whether conventional electrodes can be used for underwater wet welding and minimize the price paid due to expensive special underwater welding electrodes. Optical microscopy and SEM-EDX tests were conducted to observe and analyse the phases formed on the surface of the specimens and to determine the chemical elements contained. Carbon deficiency occurs during the underwater wet welding process due to compound reactions. In this research work it has been seen that austenite and ferrite are the dominant phases due to the loss of carbon which affects the phases formed.
