摘要: Tungsten inert gas (TIG) welding, also called as tungsten welding (GTAW), use electrode for arcing. The alloy is subjected to various temperature ranges during the process based on time, current, pulse etc. Ultrasonic velocity test coupons held at 1500 deg C 20, 40 and 60 minutes 1000 C, 1200deg period , were found be strongly influenced by elastic constants. Elastic constants shows better correlation with longitudinal than shear velocity.
