Tóm tắt

During thermal cutting, sheet metal is affected by many factors to the structure and product quality after the process. This paper presents research results about the influence of current on the heat distribution in semi-automatic cutting of sheet metal by oxygen plasma. The analysis calculation of heat that distribute at the area surrounding the cutting slot was performed by theory of heat transfer. Calculating the results of heat was compared with the experiment results of temperature of heat effect area measured by an infrared thermometer.
