ASSESSMENT OF HEAT INPUT ON MECHANICAL PROPERTIES OF MAO WELDED AZ31B MAGNESIUM ALLOY
Keywords:
Magnesium alloy, MAO welding, Tensile propertiesAbstract
In this investigation an attempt has been made to study the effect of Heat Input on tensile and microstructural characteristics of magnetic arc oscillation welded AZ31B magnesium alloy joints. Five joints were fabricated using different levels of Heat Input (290 J/mm - 379J/mm). From this investigation, it is found that the joints fabricated using a Heat Input of 334 J/mm yielded superior tensile properties compared to other joints. The formation of finer grains and higher hardness in fusion zone are the main reasons for the superior tensile properties of these joints.
