This paper reports non-destructive testing conducted on similar TIG welds between mild steel plates. The TIG welds of ms plates were produced at different current, voltage and gas flow rate. The current was varied between 120,130 and 140 amp while the voltage was varied between 12.5,14 and 15volts and gas flow rate is varied between 8,10 and 12L\min. The ultrasonic testing techniques were employed to conduct the tests; these tests were conducted on the welds to ascertain the joint integrity before characterization to have an idea of the quality of the welds. Ultrasonic inspection technique revealed the presence of Incomplete penetration defects and discontinuities in some of the welds. It was found that the welds produced at 130amp, 12.5volts and 12L/min were the best quality weld. |
