 FLUX CORED WIRE E71T-1   We specialize in producing flux cored welding wire, our R&D center works closely with the professional experts and professors from different universitis and national research institutes. Our manufacture facility owns the advanced production equipment, up -to-dated inspection/measurement instrument and the perfect evaluation and quality control systems, we have ISO 9001:2000 certificate.We have 18 production lines with the  capacity of 50,000tons per year. Our E71T-1 FCW performs very low spattering, high effective vertical welding, very stable arc and fast welding rate. The diffusible hydrogen content in the deposited metal reaches 3.5ml/100g, which significant avoid the cold cracking and porosity. We are the only flux cored welding wire supplier in China has 3YH5 certification.         --Specification conformance AWS A5.20 E71T-1 / JIS Z3313 YFW C50DR --Description   E71T-1 is a gas-shielded carbon steel wire for fabrication of mild and low carbon steel, steel-structure construction ,bridge-building and pressure vessel grades. This all position wire, E71T-1,  provides good welding performance with 100% CO2.  E71T-1 welding wire rovides consistent chemistry, steady arc, low spatter and an excellent bead appearance.   --Shielding gas 100% CO2   --Chemical Composition of deposited metal
