چکیده
According to vast applications of aluminium alloy in automobile, aerospace, and other industries, laser welding is an important technique in welding alloys. The purpose of this study is to develop a numerical model to predict temperature distribution during melting and solidification in laser welding process. The governing equation including heat transfer and phase change equations are solved by using a numerical code based on finite volume technique written with FORTRAN programming language. The results obtained from the developed model have been compared to results from experimental studies. The comparison of these data shows a desirable conformity. Finally, parametrical studies have been performed with the verified model in order to investigate the effect of operating parameters on laser welding procedure of AA6061.کلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
