Abstract
This paper investigates the root cause of an industrial fire that occurred within a high airflow rate duct system connected to a metal inert gas MIG welding operation A fullscale experiment was conducted with the aid of an infrared thermographic recording system to monitor the thermal behavior cooling rates of the flying welding spatters and splashes and visualize their interaction with cellulose filter banks Several operational scenarios were duplicated and the fire critical conditions were identified This study also provided new information about the welding spatters size speed splash angle and distribution The findings from current work might lead to effective fire mitigation strategies for industrial welding ventilation systems containing cellulose filtersThis study was supported in part by The Commonwealth of Kentucky Economic Development Office under the Department of Commercialization and Innovation program We would like to thank Richard Alloo of Toyota for his guidance and valuable comments and Bob Gregory for his editorial work
