|Title:||ETUDE NUMERIQUE DE LA VARIATION DE TEMPERAURE DANS LE SOUDAGE A L’ARC ELECTRIQUE SOUS FLUX SOLIDE DES ACIERS A FAIBLES POURCENTAGE DE CARBONE|
in progress welding
|Abstract:||Numerical study is useful as well as necessary in the assessment of the width limit of the heat affected zone (HAZ) as far as steel welding is concerned. Only limited published work has considered a mobile heat source to define the temperature variation in industrial low carbon steel (0, 19 wt. % C) when welding is in progress between the initial and final welding time [1-4]. In this present work, an approximate method of deducting HAZ width value has been developed and shown to give reasonable results. The research aspects considered herein are as follows: The effect of arc welding on microstructures, HAZ hardness and mechanical properties of industrial low carbon steel is studied. The different zones near the (HAZ) are identified and their exact size and location are determined. An adequate agreement between calculated HAZ width value, steel phase change temperatures and HAZ hardness values has been obtained.|
