SULFUR CONTENT PRECISION CONTROL TECHNOLOGY FOR CO2- SHIELDED WELDING WIRE STEEL

摘要：

　　As a kind of impurity and displaying with FeS and MnS form in steel,Sulfur can make the disadvantage effect on the performance of hot-working,welding and corrosion resistance.The high content sulfur in steel can cause the hot brittle phenomenon for the steel.For the welding steel,when the sulfur content is higher,the drawing performance of wire rod become worst and the yield of wire rod decrease.When the sulfur is lower,the automatic wire feeding performance for the gas shielded welding become worst and the weld seam is not smooth.According to the results of welding expert research,0.010%≤ S≤ 0.020%in CO2-shielded welding wire steel is reasonable.
