| Abstract: | This paper analyzes the excellent welding performance of ultra-low carbon hainitie steel Q420qE ,and disscusses its reasonable measures of the welding process with the corresponding amount of heat input. Through the heating temperature on the mechanical properties of 15MnVNq steel and the austenitic coarse test of the U.S. brands A572Gr.50 steel, speculates thermal straightening temperature range according to the experimental results of the Dashengguan Bridge about Q420qE with TMCP and TMCP ＆ tempering supplier states. |
