The article aimed to determine both numerical and theoretical solution regarding the deflection of a stainless-steel material type 316 in form of rectangular plate having a dimensions of 3 mm thickness, 250 length and 500 mm width of the plate for welding purpose. The theoretical approach which embraced in the current study is the simple plate theory (Kirchhoff's theory) and the derivation was started from this theory to predict the deflection that effect in the plate undergoing dynamic load which are represented by vibration frequency and welding process (thermal temperature) along the plate surface. A vibration action is always correlative to the welding process and causes a deflection in the plate. This deflection was calculated for four mode shape and under various thermal load (welding process). It was found that the maximum deflection during the welding process for the four mode shapes belong to the fourth one with a value of 0.0188 mm, while the lowest one is belonging to the first mode shape with a value of 0.00134 mm. The maximum deviation between the numerical and theoretical approach was found to be less than 5%.
