Ignition Mechanism of Combustible Materials in Welding and Fusing

Abstract

In recent years, many fire incidents caused by carelessness toward welding and fusing safety have occurred at industrial sites in Korea. This negligence has led to large-scale fires, resulting in devastating and irreversible national social losses. To address this issue, a safety awareness investigation was conducted by surveying welders and analyzing the major fire accidents caused by welding. In addition, a more accurate fire-generation mechanism for sandwich panels, urethane foam, and nonwoven fabrics was scientifically derived by conducting fire reproduction tests in which combustibles were surrounded by sparks during welding. Measures to prevent accidental fires were also devised.
