AMORPHOUS FLUX MATERIALS FOR FLUX-CORED WIRE
非晶态药芯焊丝药芯材料

The principle and technology to produce amorphous flux for flux-cored wires by the sol--gel process were introduced in detail. Amorphous flux powders have been made from Ti(OC4H9)4 and Si(C2H5)4 and analysed with X--ray diffraction, TGA and DTA. The results show that the amorphous fuel powders produced by the sol-gel process have homogeneous chemical compositions, low residual hydrogen content and less moisture adsorption, which can meet the need of automatic welding production and has a good future for the development and applications.
