Effect of Welding Parameters on the Mechanical Properties and Microstructure of BQ Plateastm SA 516 – 60 Grade

Abstract

A detailed study on the microstructure, phase analysis and mechanical properties, HAZ width of BQ PLATE ASME SA 516 – 60 GRADE weld metal V- joint and heat-affected zone of 10 mm thick BQ plate was carried out using metallurgical microscopy, with olimpus inverted metallurgical microscope projection system including mega pixel camera and image analysis software. The various sub-zones in the microstructure were observed in the HAZ of weld, base metal and weld pool are spheroidized, partially transformed, grain refined and grain coarsened. The main purpose of present work is to investigation and correlate the relationship between the various parameters; mechanical properties and microstructure of single “V” butt joint of Boiler Quality plate.
