Abstract
We have conducted a study on stainless steel laser-welding materials by using a laser beam for the evaluation. Stainless steel used in a rust and excellent thermal deformation has a variety of application. In this study, to improve the mechanical properties of stainless steel, a 50 W laser thermal source is used and magnetic fields are applied, on the basis of suggestions. The mechanical properties and performance are evaluated by performing a numerical analysis, tensile test, and shape, microstructure, and hardness test. The results show that the mechanical properties of improve increased speed the melting pool, tensile strength of 16 kPa rise, run into the melting zone and hardness 7 Hv.
