Rutile flux-cored wire used for low carbon steel and Grade 490MPa high strength steel Purpose: Suitable for welding in fields such as shop body, bridge, storage tank, sea project and thick board, etc. Main Characteristics: Good all-position welding, less fume, convenient and safe operation Good low temperature resisting feature; Be in conformity with requirement under -30º C Excellent welding process: Stable and mild arc with less splashing, even slag and good removability of slag Good anti-porosity of primer, smooth and beautiful welding, stable and reliable welding quality Clean and smooth wire, continuous and reliable feeding, fast welding and high efficiency Equivalent Standard: AWS A5.20/ASME SFA5.20 E71T-5 JIS Z3313 YFW-C502B Protection Gas: 100%CO2 Points for Attention: When welding middle thick plate of low carbon steel, make pre-heat (50~150º C) first before welding and keep the temperature of the layer; When making single-surface welding, in case welding data are improper, thermal crack could occur therefore Welding data should be adjusted well can then normal welding be carried out; DC negative polarity welding should be adopted; Under conditions where temperature is 10~30º C and relative humidity is 60%, welding wires can be stored for 6 months without affection upon hydrogen content of welding joint. Prevent surface of welding wire from pollution after unpacking and store it under drying condition with constant temperature and humidity to prevent it from rust and moistness.
