Abstract

This paper reports non-destructive testing conducted on similar MIG welds between mild steel plates. The MIG welds of ms plates were produced at different current, voltage and welding speed. The current was varied between 100,120 and 140 amp while the voltage was varied between 20, 25 and 30volts and welding speed is varied between 1.5,2 and 2.5mm/s. The radiographic 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. Radiography technique revealed the presence of incomplete penetration defects and discontinuities in some of the welds. It was found that the welds produced at 140amp, 20volts and 2.5mm/s were the best quality weld.
