The Comparison of the Heat Distribution and Characteristic between the Laser & SMAW Welds of 9Cr-lMo Steel.
9Cr-lMo강에 대한 Laser 및 SMAW 용접부의 열분포 특성 비교
Abstract
Recently 9Cr-1Mo azzoy is used in the Nuclear power plant due to its special properties. This material has the merit of high-strength resistance and corrosion resistance. Therefore the demand for this alloy is dramatically increased in the Nuclear power, petro-chemical complex etc. Re various research has been conducted to improve the material properties of this alloy. In spite of this circumstance, detail research in the area of welding process of this alloy is yet to be expanded In this study the numerical non-linear heat transfer analysis of laser welding which may possibly replace the conventional SMAW fabrication of 9Cr-1Mo steel has been carried out.
