Abstract

In industry, different kinds of activities are taking place such as cutting, grinding, welding, etc. Conducting these activities requires considering safety issues such as sparking that causes a fire, especially in flammable areas. This study aims to analyze the influence of the cutting pressure and welding direction on the spark distance. Three different cutting pressures include 14, 23, and 28 kPa. Two different cutting and welding positions including transverse and longitudinal directions are applied to the steel pipe. The results of this study show that, with increased cutting pressures the spark distances are also increased. The higher spark distance of cutting was observed at 360 cm and welding was 93.33 cm in longitudinal and transverse direction respectively.
