摘要：

ABSTRACT The effects of pulsing current parameters on weld pool geometry namely front height, back height, front width and back width of pulse current gas tungsten arc welded (GTAW) titanium alloy was analysed. Four factors, five levels, central composite design was used to develop empirical relationships, incorporating pulsed current parameters and weld pool geometry.
