Application of Plackett-Burman model in welding experiments : effects of welding parameters on bead shape in Cu-Ni PULSE MIG process

PLACKETT-BURMAN MODEL을 이용한 Cu-Ni합금의 PULSE MIG 용접 변수해석

The purpose of this study is to reexamine our test method in the light ofstatistical methods for data interpretation. Our trial to apply Plackett-Burman statistical model in multifactorial welding experiments shows that is saves much time and cost and extracts very accurate results. In this study, the parametric effects of bead shape on pulse MIG process in Cu-Ni alloy are investigated for verifying our trial.
